应用Empower Stats软件实现诊断准确性试验的Meta分析

Realization of Meta-analysis of diagnostic test accuracy(DTA) by using EmpowerStats software

Empower Stats软件是一款基于R语言进行数据分析的统计软件。该软件具有快速实现分析思路、全面的分析功能、直观的数据、强大的数据预处理功能、快速分享分析结果等特点。无需编程,就能运用R程序进行数据管理、处理和分析,功能强大而操作简便,所以该软件广为科研统计者所青睐。但其缺陷在于对诊断准确性试验的Meta分析不能直接得出敏感度、特异度的似然比,本文将以实例的形式系统展示Empower Stats软件用于实现诊断准确性试验Meta分析的两项模块:随机(混合)效应模型Meta分析和根据敏感度特异度生成SROC曲线。

Empower Stats software is a statistics software based on R language to realize data analysis. This software possesses the features of quickly accomplishing thinking of analysis, comprehensive function, intuitive data, powerful data preprocessing function and rapidly sharing the results. Without programming, R program can be used for data management, processing and analysis, and it is powerful and easy to operate, so the software is widely favored by scientific researchers. However, it doesn’t provide straightforward likelihood ratio of sensitivity and specificity in the Meta-analysis of diagnostic test accuracy (DTA). In the article, two modules of using EmpowerStats software to realize the Meta-analysis of DTA were systematically displayed with examples including random (mixed) effective model Meta-analysis and creating ROC curve according to sensitivity and specificity.
