Two years on, we have been alerted to an error in a box in this clinical review by Rakesh Aggarwal and Piyush Ranjan (BMJ 2004;329:1080-6, doi: 10.1136/bmj.329.7474.1080). The error occurs only in the “Full Text” (html) version of the article (not in the pdf or the printed journal). In box 5, a vital superscript value was missing: the second bullet point should read “Virological response—Decline in hepatitis B virus DNA to <105 copies/ml.”
