Instructions: the risk factors for each patient were shown on a variable axis in this nomogram, and the number of points each risk factor received was calculated by drawing a vertical line upward.Calibration curves in the training and validation cohorts (a, b). The Comparison of the diagnosis value of the nomogram by the ROC curves in the training and validation cohorts (a, b). Abbreviations: FP: false positive; TP: true positive.Decision curve for prediction of the risk of csPCa. Gray line: assume all patients will have csPCa; Black line: assume no patient will have csPCa; Red line: binary rule based on nomogram model.Baseline characteristics of the training and the validation cohort.Descriptive characteristics of patients with no PCa and PCa.Descriptive characteristics of patients with no csPCa and csPCa.Logistic regression analysis for the risk factors in the training cohort.ROC curve comparing base model with base model with AISI and PIRADS score for csPCa.Abbreviations: SEN: sensibility; SPE: specificity.
