Association between Bilirubin and Survival in Primary Biliary Cirrhosis
Primary Biliary Cirrhosis is a chronic liver disease relatively rare and mainly affects women. There are different ways to investigate the association between a biomarker and survival. Some consider only the value at baseline while others take into account the longitudinal trajectory of biomarker. Our goal is to compare three different approaches to assess the association between serum bilirubin and overall survival in PBC patients.
