Univariate and multivariate analyses of different prognostic parameters in patients with colorectal cancer by log-rank test and Cox regression analysis.

Variable	Univariate log-rank test (P-value)	Cox multivariate analysis (P-value)	Relative risk
Age	0.178	0.148	0.987
Gender	0.238	0.435	1.012
MTD	0.876	0.706	0.824
Tumor location	0.762	0.604	0.987
Depth of invasion	0.541	0.442	1.112
TNM stage	0.089	0.168	1.862
miR-217 expression	0.009	0.018	6.438

TNM, T category describes the primary tumor site; N category describes the regional lymph node involvement; M category describes the presence or otherwise of distant metastatic spread; MTD, mean tumor diameter; miR, microRNA.
