Abstract

Rereading the article “Propensity-matched analysis of patients with intrahepatic cholangiocarcinoma or mixed hepatocellular-cholangiocarcinoma and hepatocellular carcinoma undergoing a liver transplant” (DOI: 10.5306/wjco.v13.i8.688), published on August 24, we observe, with concern, that figures 3 and 4 are wrong. The authors have attached the correct figures for correction.

Key Words: Cholangiocarcinoma, Hepatocellular carcinoma, Liver, Prognosis, Recurrence, Survival analysis, Correction

Core Tip: The authors have attached the correct figures for correction rereading the article “Propensity-matched analysis of patients with intrahepatic cholangiocarcinoma or mixed hepatocellular-cholangiocarcinoma and hepatocellular carcinoma undergoing a liver transplant” (DOI: 10.5306/wjco.v13.i8.688).
TO THE EDITOR

Rereading our article “Propensity-matched analysis of patients with intrahepatic cholangiocarcinoma or mixed hepatocellular-cholangiocarcinoma and hepatocellular carcinoma undergoing a liver transplant”[1] (DOI: 10.5306/wjco.v13.i8.688), published on August 24, we observe, with concern, that figures 3 and 4 are wrong. At some point, we have mistakenly forwarded a wrong file. Therefore, we attach the correct figures for correction (Figures 1 and 2). We hope that it will be possible to replace the wrong figures with the correct ones and that this process will not be difficult. We apologize in advance for this unfortunate mistake. Of note, correction does not change the interpretation of results or conclusion.

HRs: Hazard ratios; CI: Confidence interval.
