st: Meta-Analysis of Proportions

[Chamberlain Jonviea Danielle <jonviea.chamberlain@paraplegie.ch>]

Hi,

I'm interested in performing a meta-analysis of a proportion/rate (for example, I'd like to come up with an pooled estimate of the case-fatality rate). I recently read that the Freeman-Tukey transformation should be used when using proportions. Is there a preferable way to meta-analyze proportions instead of using this transformation? If yes, what would that be and how would you perform the command in stata? Or, is it ok to not use a transformation? I attempted to use the Freeman-Tukey transformation and compared results with my meta-analysis of the non-transformed proportion and results were quite similar. Also, does anyone have any recommended texts on advanced analysis in stata that also explains the 'why' of why you'd choose one method over another? 

Thanks for your help!
