# Comparing meta-analyzed proportions

Using the meta-prop function of R, I estimated two meta-analyzed proportions (A and B). Each of these proportions comes with an estimate and 95% confidence interval.

I would like to test whether these proportions are equal (CHI-square), however this method requires that I specify the number of events and total number. If I would use the estimate and total number for both groups I could come up with these arguments; however the detail of the confidence interval etc. is lost. What can I do?

• Since you use R you might be interested in metafor-project.org/doku.php/… which does use metafor, a different package from meta, but I think you can convert the reasoning fairly easily. – mdewey Jan 9 '18 at 17:02
• @mdewey thank you a lot for your answer. This is exactly what I needed. If you post it as an answer I will accept it. – Héctor van den Boorn Jan 12 '18 at 23:20
