Cox proportional hazards regression analysis results. Hazard ratios and 95% confidence intervals are displayed for OS (black) and PFS (gray) associations with age, sex, KPS, surgery proximity (resection within 6 months of bevacizumab), tumor grade, and number of recurrences before initiating bevacizumab therapy. No significant covariates were identified between BEV and BEV/pRDR groups (Fig. 3). Abbreviations: CI = confidence interval; HR = hazard ratio; OS = overall survival; PFS = progression-free survival; PH = proportional hazard; pRDR = pulsed reduced dose rate radiation therapy.
