Summary

This study is a bidirectional cohort study. The investigators conduct a bidirectional cohort study utilizing a database in mainland China, continuously collecting demographics, clinical symptoms, and biochemical characteristics of diagnosed PBC patients. The study aims to analyze the association between varying post-treatment alkaline phosphatase (AKP) levels and complication-free survival rates, with the objective to develop and validate a predictive survival model.
