Table 3. Performance and calibration measures for the multivariable model for urinary incontinence, hematuria and pain during voiding.

Apparent measures were calculated using the complete dataset on which the model was trained; the corrected measures were adjusted for optimism as calculated with a bootstrapping procedure.
