Univariable logistic regression analyses assessing the association between predictor variables and the presence of bladder cancer in 1182 patients with painless hematuria^*

Predictors of UCB	OR	95% CI	p value	AUC, %
Age (continuous)	1.04	(1.03–1.06)	<0.0001	64.5
Gender (male vs female)	1.49	(1.04–2.15)	0.03	52.3
Smoker (past or current vs never)	3.38	(2.49–4.58)	<0.0001	64.4
Hematuria (gross vs microscopic)	2.47	(1.85–3.30)	<0.0001	60.3
Cytology (positive vs negative)	16.12	(10.98–23.66)	<0.0001	70.8
Immunocytology (positive vs negative)	30.24	(20.70–44.17)	<0.0001	84.5

UCB = urothelial carcinoma of the bladder; OR = odds ratio; CI = confidence interval; AUC = area under the curve.

^*AUC estimates are based on internal validation using 200 bootstrap samples.
