authors from the 6,000 highest-output in Hepatology, re-ranked on the composite score. Author identities come from OpenAlex disambiguation and inherit its errors: a merged record can put one name over two people’s work, and a split one can halve a career. Every row links out to the OpenAlex record so the underlying claim is checkable, and anything that looks wrong can be reported from the row. That report files a correction against the bibliographic record for a human to review — it is not a removal or delisting request, and no such route exists yet.
