Multivariate Analysis of Survival (Cox Proportional Hazards Regression Model) involving clinical variables and GBMs classification.

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