Fig. 2From: A novel post-percutaneous nephrolithotomy sepsis prediction model using machine learningMean cross-validation ROC curve of the built model. The thick blue line corresponds to the mean ROC curve, while the light blue shaded area represents the spread of all 100 ROC curves generated across the validation folds. FPR – False Positive Rate, TPR – True Positive Rate. Dashed diagonal line represents a reference random-guess AUC for comparisonBack to article page
