Prognostic characteristic of the ammonia death-related prognostic model. (A, B) Forest maps showing univariate/multivariate Cox regression analysis of clinical and molecular variables. (C) Restricted Cubic spline analysis revealed a non-linear association between AS and total survival risk. (D) Schoenfeld residual test to verify the proportional risk hypothesis. (E) Calibration curves evaluate the prediction of 1/3/5 year survival probability - observational consistency. (F-H) Decision Curve Analysis evaluated the clinical net benefit of the model at different risk thresholds
