Multivariate Analysis of Survival (Cox Proportional Hazards Regression Model) involving clinical variables and the QS of EGFR.

The Model P-value indicates the overall level of significance of the multivariate model. Aside from “Age” and “EGFR QS”, which are continuous variables, the other variables are binary. These variables distinguish between complete and partial resection and radiotherapy + temozolomide compared with radiotherapy alone. The individual P-values represent the levels of significance of the independent contributions of each variable.CI: confidence interval
