Model validation assessment based on 10-fold cross-validation of model building process for the Enriched Model including calibration plot depicting observed risk on predicted risk from at 5-year risk of kidney replacement therapy (3a) and survival function of standardized residual times for participants (3b). The calibration plot demonstrates close correspondence between observed and predicted 5-year risk and the survival function aligns closely with the expected standard exponential for strong model fit.
