Variable	No.	Univariate hazard ratio (95% CI*)	Univariate P	Multivariate hazard ratio† (95% CI)	Multivariate P
TS group (low=reference)	160	.46 (.28–.75)	.040**	.45 (.28–.73)	.032‡
Stage (IA=reference)	160	1.72 (1.06–2.78)	.029	1.76 (1.08–2.87)	.022
Sex (Women=reference)	160	1.23 (.77–1.96)	.393
ERCC1 expression	160	.994 (.986–1.002)	.130
RRM1 expression	160	.988 (.975–1.002)	.095
Performance status (0=reference)	150	1.46 (.87–2.44)	.156

^**CI indicates confidence interval.

^†Based on 160 patients because performance status was eliminated from the final multivariate analysis.

^‡Adjusted P to account for optimal cutpoint selection.
