Radiomics nomogram presented with ROC and calibration curves. A radiomics-based nomogram was established due to the training cohort, with radiomics signature, ALT, AST, GLOB and INR incorporated (a). Comparison of ROC curves between radiomics nomogram, CT-reported cirrhosis status, APRI and FIB-4 in the training (b) and validation (c) cohort. Calibration curves of radiomics nomogram in the training (d) and validation (e) cohort. ALT, alanine transaminase; APRI, aspartate transaminase-to-platelet ratio index; AST, aspartate aminotransferase; FIB-4, fibrosis-4; GLOB, globulin; INR, international normalized ratio; ROC, receiver operating characteristic
