Development and validation of the Cirrhotic Ascites Severity model—A patient‐reported outcome‐based model to predict 1‐year mortality
Rasmus Hvidbjerg Gantzel, Niels Kristian Aagaard, Hendrik Vilstrup, Hugh Watson, Henning Grønbæk, Peter Jepsen – 15 August 2022 – Ascites formation is a sign of decompensation of cirrhosis and heralds a poor prognosis. The widely used standard binary classification of ascites as diuretic‐responsive or refractory does not cover the spectrum of ascites and has limited prognostic information. We developed the Cirrhotic Ascites Severity (CIRAS) model to predict 1‐year mortality among 465 patients randomized to placebo in the satavaptan trials investigating treatment of cirrhotic ascites.
