  • Data are presented as n (%) or mean±sd, unless otherwise stated. Event: death during the follow-up period; censored: number of patients who were still alive at the end of the last interval of the follow-up. HR: hazard ratio; COPD: chronic obstructive pulmonary disease; HBV: hepatitis B virus; HCV: hepatitis C virus; NC: not computable. #: using the log-rank test, with the exception of age. : n = 46, as one patient was lost during follow-up. +: estimated by Cox regression.
