Nomogram to predict the probability of early recurrence (ER) of hepatocellular carcinoma (HCC) after microwave ablation (MWA). Predictor points are found on the uppermost point scale that corresponds to each variable. On the bottom scale, points for all variables are added and translated into the probability of HCC with progenitor phenotype. Generally, the maximum possible total points with all high-risk features present were around 240 at the bottom scale, and the ER probability of HCC was higher than 90% when the total points exceeded 224. Liner predictor = 0.811 × ill-defined margin (0: No; 1: Yes) + 1.208 × lack of capsule enhancement (0: No; 1: Yes) + 1.708 × ADC (0: ≥ 1.272 × 10−3 mm2/s; 1: < 1.272 × 10−3 mm2/s) + 1.081 × ΔADC (0: ≥ 0.283 mm2/s; 1: < 0.283 mm.2/s) + 0.113 × EADC (0: ≥ 0.316; 1: < 0.316) Cutoffs to generate the risk groups: ≤ 2.673 (Low risk); > 2.673 (high risk)
