【摘要】 生存资料的Meta分析越来越多。从原始文献计算出风险比(HR)及其95%可信区间,实际频数和理论频数的差值(O-E)及其标准差后,可以使用Review Manager(RevMan)、Stata和R等软件计算合并HR。RevMan软件简单易学,但存在一定的局限;Stata和R软件功能强大,灵活多样,能够绘制多种图形,但需要进行适当的编程。更多还原

【Abstract】 Meta-analysis of survival data is becoming more and more popular. The data could be extracted from the original literature, such as hazard ratio(HR) and its 95% confidence interval, the difference of actual frequency and theoretical frequency(O- E) and its standard deviation. The data can be used to calculate the combined HR using Review Manager(RevMan), Stata and R softwares. RevMan software is easy to learn, but there are some limitations. Stata and R software are powerful and flexible, and they are able to draw a variety of graphics, however, they need to be programmed to achieve.更多还原
