Hi Rosa, This looks like a mix of a R problem and a statistical problem. For the statistical part I think you are going to need to find a statistician/adviser to sit down with and workout what you want to measure and whether it is possible. For the R part it might be more useful to ask specific question about metafor, what happened when you tried to use it? Do you have an error message or a small example you could post so we could rerun your analysis?

One off my problems, I think, is that: 1st. it’s the first time :) 2. I only have data for 1 arm as you can see on the data that follows. ARTIGO qt tt qc tc Personal Notes qt2 Giuliani M. (2014) - - 1515 1862 only MSM. 347 Diaz A. (2015) - - - - only MSM (n=3081) 2499 Niedźwiedzka-Stadnik M. (2015) 828 1098 - - 326 Hoenig M. (2015) - - 8506 - MSM (n=8925) 419 Wu H.

Is it possible to conduct a met analysis concerning the risk of hiv among MSM relative to the ones that are not MSM? or simply concerning the risk of hiv among MSM???? If yes, How? Metafor? I’ve tried, but wasn’t succeed :( Best, RO Atenciosamente, Rosa Oliveira -- ____________________________________________________________________________ Rosa Celeste dos Santos Oliveira, E-mail: rosit...@gmail.com <mailto:rosit...@gmail.com> Tlm: +351 939355143 Linkedin: https://pt.linkedin.com/in/rosacsoliveira <https://pt.linkedin.com/in/rosacsoliveira> ____________________________________________________________________________ "Many admire, few know" Hippocrates ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.__________________________________________________________________________________________________________ This email has been scanned for the NSW Ministry of Health by the Websense Hosted Email Security System.
