Figure 2. Receiver operating characteristics (ROC) curve analysis (A) and box plots (B) of Index 1, 2 in Training Group and Validation Group for discriminating PC from non-PC.

Figure 2

A. Index1, Index2 and CA19-9 yielded AUCs of 0.968 (95%CI, 0.947-0.989), 0.967 (95%CI, 0.945-0.989) and 0.895 (95%CI, 0.838-0.952) respectively, in the training group. In the validation group, the AUC was 0.915 (95%CI, 0.878-0.953) for index1, 0.920 (95%CI, 0.883-0.957) for index2 and 0.862 (95%CI, 0.809-0.915) for CA19-9 respectively. B. Box plots with traditional Tukey whiskers, showing 1.5 times the interquartile distance. The horizontal line in the middle of each box indicates the median, and the points beyond the whiskers are outliers. The box plots of both indexes showed significant difference between PC group and non-PC group (***, P<0.001).
