Questionnaire - MD Anderson Symptom Inventory - Brain Tumor (MDASI-BT). Results reflect patient-reported symptoms. Here they are presented as a mean change: the difference in the weighted mean of symptom severity and interference scores at baseline versus at 6 months. The difference between these scores is the mean change reported below. The MD Anderson Symptom Inventory has a scale of 0-10, 0 being not present and 10 being as bad as the patient could imagine. The calculated score change has a range of -10 to 10; -10 being the best. Change in score is calculated as the composite weighted means of symptom severity and interference at 6 months minus the composite weighted means of symptom severity and interference at baseline.

The Karnofsky Performance Status (KPS) is a tool designed to assess a cancer patient's functional status. Scores range from 0 to 100 with higher scores indicating better function. Scores 90-100 indicate that the patient is independent and can perform daily activities with little to no effort. A score of 80 indicates that the patient can conduct their normal activities with some effort. A score of 70 indicates that a patient can care for themself but cannot carry on normal activities independently. Here we report the least squares mean Karnofsky Performance Score for each arm based on the Karnofsky Performance Status Scale at each timepoint from Baseline to 12 Months post-baseline.
