Multivariate analysis for the prediction of false-negatives for high-grade urothelial carcinoma

Variables	Multivariate
	ORs*	95% CI	P values*
Evaluated using CS rather than TPS	2.26	1.08–4.77	0.03
Prior recurrence status	0.47	0.27–0.79	< 0.01
Prior TUR within 90 days	0.71	0.36–1.38	0.31
Multiple tumor	1.59	0.91–2.78	0.11
Solid tumor	1.99	1.03–5.00	< 0.01
Large tumor (≥ 3 cm)	2.27	0.49–8.07	0.33
