Table 3. Multivariate Cox regression analysis on 5-year overall and disease-specific survival of 300 renal cancer patients.

Variable*	Overall survival			Disease-specific survival
	Hazard ratio	95% CI†	P	Hazard ratio	95% CI	P
RUNX3	0.315	0.163 to 0.607	0.001	0.182	0.083 to 0.398	0.000
Age	0.970	0.515 to 1.827	0.925	0.884	0.423 to 1.846	0.743
Tumor size	1.473	1.004 to 2.269	0.041	1.532	1.205 to 2.636	0.015
TNM stage	1.653	1.476 to 3.135	0.016	1.721	1.213 to 2.437	0.018

^*Coding of variables: RUNX3 was coded as 1 (low), and 2 (high). Age was coded as 1 (≤56 years), and 2 (>56 years). Tumor size was coded as 1 (≤7 cm), and 2 (>7 cm). TNM stage was coded as 1 (I-II), and 2 (III-IV).

^† CI: confidence interval.
