Fig. 6. Kaplan–Meier and log-rank analyses of prognostic factors assessed in multivariable analysis using a COX proportional hazards model.

Median values were taken as cutoff limits when the two groups were compared. Survival analyses were performed using the Kaplan–Meier method for the estimation of event rates, and a log-rank test was used for survival comparisons between patient groups. The P value was 5%. PHB expression level (p < 0.01) and histological G stage (p < 0.05) both were independent prognostic factors, but the others risk factors, although showing the classical tendencies, did not appear to impact on the prognosis independency.
