Erratum

Erratum:“A population-based study of hepatitis D virus as potential risk factor for hepatocellular carcinoma.” Ji J, Sundquist K, Sundquist J. [J Natl Cancer Inst. 2012 104 (10): 790-792] In the second paragraph, lines 12–18, the codes for acute HDV infection in HBV carriers were incorrect. This sentence should read: “Patients were identified according to the Tenth Revision of the International Classification of Diseases using the following codes: B181 (chronic HBV infection without HDV), B180 (chronic HBV infection with HDV), and B170, B160, and B161 (acute HDV infection in HBV carriers).” The authors regret this error.
