Note to authors:

ALL ARTICLES MUST BE SUBMITTED ONLINE. Once you have prepared your manuscript according to the Instructions below, Please pay particular attention to the sections on Conflict of Interest Declaration and Figure Preparation.

Please visit http://mc.manuscriptcentral.com/ndt to submit to NDT. Instructions on submitting your manuscript online can be viewed here.

## 1. AIMS AND SCOPE

NDT – Basic and Clinical Science is an official publication of the European Renal Association-European Dialysis and Transplant Association. NDT publishes Editorials, Reviews and original research. Rapid communications, exceptional cases and (only) online E-letters to the Editor commenting on papers previously published in the journal are also considered. The journal covers the whole territory of nephrology research including experimental work in animal models and molecular biology studies. In the Clinical Science section we consider clinical trials (RCT have a priority in our journal), observational studies at large and original works on health economy as applied to nephrology. We aim to cover the whole spectrum of kidney disease research, from clinical nephrology to haemodialysis and peritoneal dialysis as well as renal transplantation.

Only single patient and small case-series providing novel insights – ranging from cellular or molecular levels to the clinical level – or papers describing novel clinical observations will be accepted for publication in NDT .

NDT may accept high-quality, peer-reviewed supplements. Please contact supplements@oup.com in the first instance for further information. Abstracts from the annual ERA-EDTA congress are published as a supplement to NDT each year.

NDT only accepts online submissions. Please visit http://mc.manuscriptcentral.com/ndt.
You will also find more complete submission instructions at this site.

## 2. AUTHORS: ROLES AND RESPONSIBILITIES

The journal takes publication ethics very seriously. If misconduct is found or suspected after the manuscript is published, the journal will investigate the matter and this may result in the article subsequently being retracted.

Authors should observe high standards with respect to publication ethics as set out by the Commission on Publication Ethics (COPE) and International Committee of Medical Journal Editors (ICMJE). Falsification or fabrication of data, plagiarism, including duplicate publication of the author's own work without proper citation, and misappropriation of the work are all unacceptable practices. Any cases of ethical misconduct are treated very seriously and will be dealt with in accordance with the COPE guidelines. If misconduct is found or suspected after the manuscript is published, the journal will investigate the matter and this may result in the article subsequently being retracted.

Each author should have participated sufficiently in the work to take public responsibility for the content. This participation must include:

1. Conception or design, or analysis and interpretation of data, or both.
2. Drafting the article or revising it.
3. Providing intellectual content of critical importance to the work described.
4. Final approval of the version to be published. (See Br Med J 1985; 291: 722-723.)

Manuscripts should bear the full name and address, with telephone, fax, and email of the author to whom the proofs and correspondence should be sent (corresponding author). For all authors, first name and surname should be written in full.

In a covering letter, the individual contribution of each co-author must be detailed. This letter must contain the statement: 'the results presented in this paper have not been published previously in whole or part, except in abstract form'. Should your manuscript be accepted for publication, you will be required to give signed consent for publication (see copyright section).

On acceptance, the corresponding author will be advised of the approximate date of receipt of proofs. Proofs must be returned by the author within 48 hours of receipt.

To accelerate publication, only one set of PDF proofs is sent to the corresponding author by email. This shows the layout of the paper as it will appear in the Journal. It is, therefore, essential that manuscripts are submitted in their final form, ready for the printer. Proof-reading must be limited to the correction of typographical errors. Any other changes involve time-consuming and expensive work and may not be permitted at this stage. If additions are necessary, these may be made at the end of the paper in a Note in Proof. Major changes may be subject to editorial approval.

Authors are referred to the statement on uniform requirements for manuscripts submitted to biomedical journals prepared by an international committee of medical journal editors. (Br Med J 1982; 284: 1766-1770, Ann Intern Med 1982; 96: 766-771.)

### Protection of Human Subjects and Animals in Research

When reporting experiments on animals, authors should indicate whether the institutional and national guide for the care and use of laboratory animals was followed.
In particular, NDT recommends compliance with the DIRECTIVE 2010/63/EU of the European Parliament for authors submitting from the European area, and compliance with the Guide for the Care and Use of Laboratory Animals for non-European authors.

When reporting experiments on human subjects, authors should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000 (5). If doubt exists whether the research was conducted in accordance with the Helsinki Declaration, the authors must explain the rationale for their approach and demonstrate that the institutional review body explicitly approved the doubtful aspects of the study.

Patient consent
Authors should state in their paper that informed consent has been obtained from the subjects (or their guardians) as specified in the ICMJE Reccomendations

## 3. TABLES

All tables must be numbered consecutively and each must have a brief heading describing its contents. Any footnotes to tables should be indicated by superscript characters. Tables must be referred to in the main text in running order. All tables must be simple and not duplicate information given in the text.

## 4. FIGURE PREPARATION

Please be aware that the requirements for online submission and for reproduction in the journal are different: (i) for online submission and peer review, please upload your figures either embedded in the word processing file or separately as low-resolution images (.jpg, .tif, .gif or. eps); (ii) for reproduction in the journal, you will be required after acceptance to supply high-resolution .tif files (1200 d.p.i. for line drawings and 300 d.p.i. for colour and half-tone artwork) or high-quality printouts on glossy paper. We advise that you create your high-resolution images first as these can be easily converted into low-resolution images for online submission.

We would encourage authors to generate line figures in colour using the following colour palette:

Blue (CMYK definition - 96/60/2/1 / RGB definition – 0/101/172)
Orange (CMYK definition - 0/71/88/0 / RGB definition – 243/110/53)
Pink (CMYK definition - 0/100/50/0 / RGB definition – 237/20/90)
Yellow (CMYK definition - 1/29/94/0 / RGB definition – 249/185/40)
Green (CMYK definition - 77/10/96/2 / RGB definition – 59/162/75)
Magenta (CMYK definition - 65/98/28/25 / RGB definition – 97/33/94)

In order to have consistency throughout the journal, the publishers reserve the right to re-draw figures, where necessary, with the appropriate colours from the palette. Authors will have an opportunity to correct inappropriate changes at the proof correction stage.

For useful information on preparing your figures for publication, go to http://cpc.cadmus.com/da/index.jsp. Figures will not be relettered by the publisher. The journal reserves the right to reduce the size of illustrative material. Any photomicrographs, electron micrographs or radiographs must be of high quality. Wherever possible, photographs should fit within the print area of 169 x 235 mm (full page) or within the column width of 82 mm. Photomicrographs should provide details of staining technique and a scale bar. Patients shown in photographs should have their identity concealed or should have given their written consent to publication. Normally no more than six illustrations will be accepted for publication in the print issue without charge.

Image acquisition and analysis

If primary experimental data are presented in the form of a computer-generated image any editing must be described in detail. A linear (rather than sigmoidal) relationship between signal and image intensity is assumed. Unless stated otherwise, it will be assumed that all images are unedited.

Inappropriate manipulation of images to highlight desired results is not allowed. Please adhere to the following guidelines to accurately present data:
• No specific feature within an image may be enhanced, obscured, moved, removed, or introduced.
• The grouping of images from different parts of the same gel, or from different gels, fields, or exposures (ie, the creation of a "composite image") must be made absolutely explicit by the arrangement of the figure (ie, using dividing lines) and explained in the figure legend.
• Adjustments of brightness, contrast, or colour balance are acceptable if they are applied to the whole image and as long as they do not obscure, eliminate, or misrepresent any information present in the original, including the background.
• Non-linear adjustments (eg, changes to gamma settings) must be disclosed in the figure legend.
• Alteration of brightness or contrast that results in the disappearance of any features in a gel (either bands or cosmetic blemishes) or similar alterations in other experimental images is strictly forbidden.

Authors should retain unprocessed images and metadata files, as the Journal may request them during manuscript evaluation, and/or after publication should there be a query relating to a specific figure. Files that have been adjusted in any way should be saved separately from the originals, in a non-compressed format. Compressed formats, such as JPG, should only be used for presentation of final figures, when requested, to keep file sizes small for electronic transmission. The Journal reserves the right to use image analysis software on any submitted image.

Permissions

If any tables, illustrations or photomicrographs have been published elsewhere, written consent for re-publication (in print and online) must be obtained by the author from the copyright holder and the author(s) of the original article, such permission being detailed in the cover letter.

Third-Party Content in Open Access papers

If you will be publishing your paper under an Open Access licence but it contains material for which you do not have Open Access re-use permissions, please state this clearly by supplying the following credit line alongside the material:

Title of content
Author, Original publication, year of original publication, by permission of [rights holder]

This image/content is not covered by the terms of the Creative Commons licence of this publication. For permission to reuse, please contact the rights holder.

## 5. ABBREVIATIONS

Authors should not use abbreviations in headings and figure legends should be comprehensive without extensive repetition of the Subjects and Methods section. Authors are advised to refrain from excessive use of uncommon abbreviations, particularly to describe groups of patients or experimental animals.

Non-proprietary (generic) names of products should be used. If a brand name for a drug is used, the British or International non-proprietary (approved) name should be given. The source of any new or experimental preparation should also be given.

## 7. REFERENCES

The references should be numbered in the order in which they appear in the text. References to published abstracts should be mentioned in the text but not in the reference list.

At the end of the article the full list of references should give the name and initials of all authors unless there are more than six, when only the first three should be given followed by et al. The authors' names should be followed by the title of the article, the title of the Journal abbreviated according to the style of Index Medicus, the year of publication, the volume number and the first and last page numbers. References to books should give the title of the book, which should be followed by the place of publication, the publisher, the year and the relevant pages.

Note: In the online version of NDT, there are automatic links from the reference section of each article to Medline. This is a useful feature for readers, but is only possible if the references are accurate. It is the responsibility of the author to ensure the accuracy of the references in the submitted article. Downloading references direct from Medline is highly recommended.

## 8. SUPPLEMENTARY MATERIAL

Supporting material that is not essential for inclusion in the full text of the manuscript, but would nevertheless benefit the reader, can be made available by the publisher as online-only content, linked to the online manuscript. There is no charge for the publication of online-only supplementary data/tables/figures. Such material should not be essential to understanding the conclusions of the paper, but should contain data that is additional or complementary and directly relevant to the article content. Such information might include more detailed methods, extended data sets/data analysis, or additional figures (including colour).

All text and figures must be provided in suitable electronic formats (instructions for the preparation of Supplementary material can be viewed here). All material to be considered as Supplementary material must be submitted at the same time as the main manuscript for peer review. It cannot be altered or replaced after the paper has been accepted for publication. Please indicate clearly the material intended as Supplementary material upon submission. Also ensure that the Supplementary material is referred to in the main manuscript where necessary.

## 9. COLOUR ILLUSTRATIONS

Colour illustrations are accepted, but the authors will be required to contribute to the cost of the reproduction. Colour figures will incur a printing charge of £350/$600/€525 each (this does not apply to invited contributions). Orders from the UK will be subject to the current UK VAT charge. For orders from elsewhere in the EU you or your institution should account for VAT by way of a reverse charge. Please provide us with your or your institution’s VAT number. Illustrations for which colour is not essential can be reproduced as black and white images in the printed journal and, additionally, in colour as online Supplementary material. This option is not subject to colour charges. Authors should indicate clearly that they would like to take up this option in the covering letter and on the figures. The availability of additional colour images as Supplementary material should be mentioned where relevant in the main text of the manuscript. Instructions on how to submit colour figures as Supplementary material can be viewed online. ## 10. COPYRIGHT Please note that the journal now encourages authors to complete their copyright licence to publish form online Upon receipt of accepted manuscripts at Oxford Journals authors will be invited to complete an online copyright licence to publish form. Please note that by submitting an article for publication you confirm that you are the corresponding/submitting author and that Oxford University Press ("OUP") may retain your email address for the purpose of communicating with you about the article. You agree to notify OUP immediately if your details change. If your article is accepted for publication OUP will contact you using the email address you have used in the registration process. Please note that OUP does not retain copies of rejected articles. It is a condition of publication in the Journal that authors grant an exclusive licence to the Journal, published by Oxford University Press on behalf of the European Renal Association-European Dialysis and Transplant Association. This ensures that requests from third parties to reproduce articles are handled efficiently and consistently and will also allow the article to be as widely disseminated as possible. In assigning the licence, authors may use their own material in other publications provided that the Journal is acknowledged as the original place of publication and Oxford University Press is notified in writing and in advance. ## 11. TRANSPARENCY DECLARATION & ETHICS All authors must make a formal declaration at the time of submission indicating any potential conflict of interest. This is a condition of publication and failure to do so will delay the review process. Such declarations might include, but are not limited to, shareholding in or receipt of a grant, travel award or consultancy fee from a company whose product features in the submitted manuscript or a company that manufactures a competing product. You will be required to provide this information during the online submission process. In addition , in the interests of openness, ALL papers submitted to NDT MUST include a ‘Transparency declarations’ section (which should appear at the end of the paper, before the ‘References’ section) within the article. We suggest authors concentrate on transparency declarations (i.e. conflicts of interest) of a financial nature, although relevant non-financial disclosures can also be made. Authors should either include appropriate declarations or state ‘None to declare’. Importantly, the declarations should be kept as concise as possible, should avoid giving financial details (e.g. sums received, numbers of shares owned etc.), and should be restricted to declarations that are specific to the paper in question. Authors will of course need to consider whether or not the transparency declarations need to be amended when revisions are submitted. Please click here to consult the COPE guidelines on conflict of interest. The editors’ declarations of interest statements can also be viewed online. This Journal takes publication ethics very seriously. If misconduct is found or suspected after the manuscript is published, the journal will investigate the matter and this may result in the article subsequently being retracted. ## 12. CROSSCHECK The NDT editorial team reserves the right to use CrossCheck. CrossCheck is an initiative started by CrossRef to help its members actively engage in efforts to prevent scholarly and professional plagiarism. By submitting your manuscript to the journal it is understood that this it is an original manuscript and is unpublished work and is not under consideration elsewhere. Plagiarism, including duplicate publication of the author’s own work, in whole or in part without proper citation is not tolerated by the journal. ## 13. PREPARATION OF MANUSCRIPTS TO BE PUBLISHED IN NDT ### Language editing Particularly if English is not your first language, before submitting your manuscript you may wish to have it edited for language. This is not a mandatory step, but may help to ensure that the academic content of your paper is fully understood by journal editors and reviewers. Language editing does not guarantee that your manuscript will be accepted for publication. If you would like information about such services please click here. There are other specialist language editing companies that offer similar services and you can also use any of these. Authors are liable for all costs associated with such services. ## Fast Track - publication within 6 weeks Fast Track allows publishing high impact articles submitted to NDT to be prioritized for publication. Essential requirements for Fast Track are: - Paper is very likely to have a major impact on current knowledge in nephrology. - Readership may benefit from this publication as it may represent an important advancement in a particular study field. Authors who believe their manuscript complies with the above should address their request in their cover letter. A dedicated manuscript category for submission is available in the online system: https://mc.manuscriptcentral.com/ndt Please note that only original articles will be considered for Fast Track. After evaluation by the Editor-in-Chief, the manuscripts that have been selected will undergo fast peer-review and will be published within 6 weeks after submission.
