Mar 4, 2016 at 17:45 comment added John Thank you. I will try this if no one is able to provide an appropriate formula for performing a t-test or similar. If I use metafor package, for example, how do I code the agegrp for the purposes of meta-regression? All I know is if they are above or below 50.
