Dear all, I use R 3.1.1 for Windows.
I performed two different meta-analysis assessing the prognostic value of two different tests in patients with coronary artery disease. The study included in the two analysis are different. The variable of interest in dichotomous (normal/abnormal result) for both tests. The effects size is hazard ratio and its standard error (ln units) for both meta-analysis. I would like to statistically compare the two summary hazard ratios and 95% CI (eform) obtained from the two meta-analysis. For one meta-analysis: HR 3.12 (95% CI 2.2 - 4.1) For the other: HR 1.25 (95% CI 1.03 - 2.6) It is possible or I'm comparing apples with oranges? Any suggestion is welcome. ------------------------------------------------------- Mario Petretta Associate Professor of Internal Medicine Department of Translational Medical Sciences Naples University Federico II Italy --- Questa e-mail รจ stata controllata per individuare virus con Avast antivirus. http://www.avast.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
