All were retrospective, with sample sizes ranging from 140 to 122,386 and CAUTI incidence from 1.3 to 24.7%. Logistic regression predominated (11 of 13 reports). Derivation AUC values ranged from 0.611 to 0.993; nine exceeded 0.800. The most frequently identified predictors were age, catheter dwell time, diabetes mellitus, level of consciousness, and serum albumin. All 13 reports were rated high overall risk of bias by PROBAST, driven principally by temporal leakage \u2014 the incorporation of time-varying predictors into models intended for use at catheter insertion \u2014 insufficient events-per-variable ratios, data-driven variable selection, and near-universal absence of external validation. Only two reports conducted external validation (AUC\u202f=\u202f0.758 and 0.970).
