  1. Proportional hazard Cox regression Chi2 = 20.20 - df = 4 - P = 0.00046. Groups are indicated for each variable. Only stage and grade show a higher coefficient of regression (beta) than their standard error, thereby attributing them an independent prognostic significance.*(low/up) 95% confidence interval.
