Multivariate correlation analysis of OCT1, OCT3, and MDR1 expression with OS and RFS

P values were determined using Cox proportional hazard models.

Expression of	OS			RFS
Expression of	P	HR	95% CI	P	HR	95% CI
OCT1	0.600	2.28	0.49–10.53	0.620	1.64	0.57–4.75
OCT3		0.45	0.07–2.69		0.80	0.27–2.41
MDR1		0.93	0.15–5.62		0.64	0.21–1.90

CI, confidence interval; HR, hazard ratio.
