TABLE 3.

Prediction Results of the 91-gene qRT-PCR Signature in the Validation set (n = 101).

	RSF*	Cox model**	log-rank test***
	Test error rate	P	HR	95%CI	P
	26.6%	5.21e-09
Low-risk			1		0.0008
Medium-risk			2.82	1.16 – 6.88
High-risk			4.42	1.88 – 10.42

^*RSF prediction model built from 439 training set including 91 genes, stage and age;

^**Mortality risk index (MRI) as continuous value, likelihood ratio test (LRT) was used, univariate Cox model;

^***MRI separated test patients to 3 risk groups (low, medium and high-risk, 1/3rd in each group)
