Multivariate analysis of prognostic based on OS.

Characteristics	Favorable prognosis			Poor prognosis
	β	OR (95%CI)	value	β	OR (95%CI)	value
Histological grade	1.262	3.533 (0.217, 46.143)	0.336	−0.923	0.397 (0.132, 1.198)	0.101
NERF	−2.535	0.079 (0.006, 1.052)	0.055	−1.802	0.165 (0.0.045, 0.605)	0.007
nSVZE	−0.07	0.468 (0.094, 2.328)	0.353	−0.541	0.582 (0.167, 2.026)	0.395

OS, overall survival; favorable prognosis, OS ≥ 660 days; poor prognosis, OS＜660 days; β, regression coefficient; OR, odds ratio; FLAIR, fluid-attenuated inversion recovery; NERF, new enhancement beyond the radiation field; nSVZE, new subventricular zone enhancement.
