Table 2 Evaluating the overfitting of the prediction models

From: CT-based peritumoral radiomics signatures to predict early recurrence in hepatocellular carcinoma after curative tumor resection or ablation

Models AUC [95%CI] P
Training Set Validation Set
PT-RO 0.80 [0.72, 0.89] 0.79 [0.66, 0.92] 0.47
T-RO 0.82 [0.74, 0.90] 0.62 [0.46, 0.79] < 0.01
PT-E 0.64 [0.56, 0.72] 0.61 [0.47, 0.74] 0.11
  1. AUC area under the curve, CI Confidence Interval, PT-RO peritumoral radiomics, T-RO tumoral radiomics, PT-E peritumoral enhancement; P-value reflected the differences between the training and validation cohorts, and P values of less than 0.05 (two-sided) were considered statistically significant
