Evidence-based radiologist-supervised automated Liver Imaging Reporting and Data System categorization for the diagnosis of hepatocellular carcinoma

Figure 5 Categorization results of Liver Imaging Reporting and Data System grade 3, 4, and 5. A: Overall accuracy of center 1 (left), center 2 (middle), and center 3 (right); B: Quadratic weighted Cohen’s kappa coefficient of center 1 (left), center 2 (middle), and center 3 (right). For the three comparison methods, the mean value and 95% confidence intervals from repeated training for learning-based methods (5-fold cross validation repeated 5 times; 25 models) are indicated on the column bars. Evidence-based radiologist-supervised automated Liver Imaging Reporting and Data System is deterministic (fixed algorithms and thresholds averaged across folds), so no training-induced variability/error bars are shown. ^aP < 0.05.
