Overall survival analyses according to treatment group in all patients before propensity score matching. The median overall survival (OS) was 17.9 months for patients receiving whole-brain radiation therapy plus focal radiation boost (WBRT+boost), 8.7 months for patients receiving whole-brain radiation therapy (WBRT) alone, and 14.5 months for patients receiving stereotactic radiosurgery (SRS) alone. WBRT+boost group led to a longer OS over WBRT alone group (HR, 1.82; 95% CI, 1.30–2.55; P < 0.001)
