Survival from the first CCgR, according to Sokal risk.30 

The overall log-rank test is significant (P < .0001). The 10-year survival is 89% (95% CI, 81%-98%) for low-risk patients versus 70% (95% CI, 49%-91%) for intermediate-risk patients (P = .04, log-rank test). The survival of high-risk patients is much shorter (P < .0001 versus low risk,P = .003 versus intermediate risk, log-rank test).
