Variate: clinical traits; HR (M_HR): Hazard Ratio values in univariate (multivariate) Cox regression analysis; CI95% (M_CI95%): 95% confidence interval of HR in univariate (multivariate) Cox regression analysis; z_score (M_z_score): value of z test in univariate (multivariate) Cox regression analysis; p value (M_P_value): p value of univariate (multivariate) Cox regression analysis, <0.05 is significant.
