生存资料的Meta分析越来越多,但是大部分原始文献并没有全面报告实际死亡数(O)、理论死亡数(E)、风险比(HR)及其方差(V),本文总结了O-E、HR和V等指标的多种转换公式。希望研究者能够灵活应用这些公式计算生存资料Meta分析的必备指标,并采用HR进行生存资料的Meta分析。
Meta-analysis of survival data is becoming more and more. However, most of the original literature did not offer the comprehensive porting: logrank observed events (O), logrank expected events (E), hazard ratio (HR) and logrank variance (V). This paper summarized a variety of methods about how to transform O-E, HR and V. We hope that the researcher can use the methods freely, and use HR in the recta-analysis of survival data.
