Confirmation of ALL AS-based prognostic signature. a LASSO coefficient profiles of the whole AS events. b Ten‐time cross‐validation for tuning parameter selection in the lasso regression. c Heatmap of the ALL signature AS events PSI value in HCC. The color from red to blue shows a trend from high expression to low expression. d Distribution of ALL signature risk score. e The survival status and duration of HCC patients. f Kaplan–Meier curve presenting survival in the high-risk and low-risk sets. g ROC analysis of the risk scores for overall survival prediction. The AUC was calculated for ROC curves, and sensitivity and specificity were calculated to assess score performance. Proportional hazards model results. h Univariate Cox regression results. i Multivariate Cox regression results
