The results of additional analyses.

OS: overall survival; PFS: progression-free survival; TMZ: temozolomide; RT: radiotherapy;*To remove the slight asymmetry of the funnel plots, four studies were trimmed for OS analysis and one for PFS analysis.#Random-effect model was used despite I2 statisticOS：总生存期（overall survival）；PFS：无进展生存期（progression-free survival）；TMZ：替莫唑胺（temozolomide）；RT：放疗（radiotherapy）。*为消除漏斗图的轻微不对称性，共对4项研究进行修剪以用于总生存期分析，对1项研究进行修剪以用于无进展生存期分析。#尽管存在I²统计量，仍采用随机效应模型。
