【摘要】 目的:探讨用Stata软件完成临床试验四格表资料M eta分析的方法。方法:用Stata对实例进行参数估计。结果:进行了临床试验四格表资料的M eta分析,结合实例,介绍计算综合OR、RR、RD所用到的Stata命令及输出结果。结论:用Stata可高效、快速完成M eta分析。M eta分析的固定效应模型,可能导致总效应以及个体效应的不确定性的过低估计。更多还原

【Abstract】 Objective:To explore application of Stata for efficiently complete methods of Meta analysis for 2×2 tables from the multi-center clinical trialsl.Methods:Statistic data from testbook data of examples of calculating have been collected,using simple Stata command for each example.Results:Meta analysis was made by using Stata.A full analysis was illustrated by a published example.Conclusion:Stata is better in operating than other statistics software.Statistic analysis can be efficiently completed by using Stata.The solution presented in this paper is not only more appropriate than other proposed statistics methods,but also easy toimplement by applied researchers.更多还原
