Results of meta-analysis comparison of ART and SRT.

ART = adjuvant radiotherapy; SRT = salvage radiotherapy; BFFS: Biochemical Failure-Free Survival; DFS: disease-free survival; OS: overall survival; MFS: Metastasis-free survival HR: hazard ratio; RR: risk ratio; df = degrees of freedom; CI = confidence interval; ¶: Included studies applied HR; : Included studies applied RR.ART：辅助放疗（adjuvant radiotherapy）；SRT：挽救性放疗（salvage radiotherapy）；BFFS：无生化失败生存（Biochemical Failure-Free Survival）；DFS：无病生存（disease-free survival）；OS：总生存（overall survival）；MFS：无转移生存（Metastasis-free survival）；HR：风险比（hazard ratio）；RR：相对危险度（risk ratio）；df：自由度（degrees of freedom）；CI：置信区间（confidence interval）；符号¶表示：纳入研究采用了风险比；符号: 表示：纳入研究采用了相对危险度
