MGMT and neoplasm: As an example, application of the prognostic nomogram to calculate the hazard score based on the estimated vector from the Cox regression (XB); a 60 year old patient with a partially resected tumor, using corticosteroids, ECOG PS = 1, unifocal disease, and unmethylated MGMT, would have a calculated hazard score of 2.13 and according to the established prognostic index, be classified as the prognostic group Poor (XB > 1.98).
