The authors demonstrate that the assessment of readily available and objective parameters can stratify patients according to the risk of disease progression. Patients with primary sclerosing cholangitis (PSC) usually develop progressive liver fibrosis and end-stage liver disease within 10–20 years.2 Simple and non-invasive means for disease stratification and prediction of prognosis are urgently needed. Indeed, the International PSC Study Group recently declared the research on surrogate end-point markers as a high-priority task,3 since several clinical studies investigating novel treatment strategies …
