Probability of global quality of life scores with increasing age at presentation. The global quality of life is based on a question which asks patients how much patients agree with the statement “PBC has affected my quality of life” (1 or 2 represents disagreeing with the statement (strongly or weakly), 3: Neither Agreeing nor Disagreeing, 4 or 5 represents agreeing (weakly or strongly). The younger patients are at presentation the more likely they are to describe poor quality of life (4 or 5), the older they are the more likely they are to describe good quality of life (1 or 2).
