I-score (two-category) distribution across TNM stages and the predictive accuracy of each model in the two cohorts. a A low I-score is associated with advanced TNM stages in both discovery cohort (χ2 = 9.74, P = 0.002) and validation cohort (χ2 = 4.93, P = 0.026). b The iAUC (resampling with 1000 times bootstrapping) for each model is shown as a box-and-whisker plot; median (lines), interquartile range (boxes), 2.5–97.5 percentile (whiskers). iAUC integrated area under the curve
