The multiple linear regression model incorporated several candidate predictors (“estimated effect on months until recurrence”, “[95% confidence interval]”), including age at diagnosis (0.1, [−0.1, 0.3]), ECOG functional status at presentation (−0.3, [−3.3, 2.8]), tumor MGMT methylation positivity (5.1, [−1.6, 11.7]), chemotherapy treatment (4.1, [−5.6, 14.0]), radiation treatment (11.5, [−5.8, 28.9]), and resection treatment (13.3, [−1.4, 27.9]). The gene discussed is MGMT; the disease is neoplasm.
