Dear list,

in extension of the help by Wolfgang Viechtbauer from March this year 
we wonder about an additional aspect in our data (so far we have 
restricted our analyses to the effects of different agents on PD 
symptoms). The question we now have is whether we can do a similar 
three-level hierarchical meta-analysis for events/proportions. To 
briefly summarize, we would like to model the occurrence of adverse 
events for all agents and use the study type as a moderator. However, we 
are aware that "RR" or "OR" are poor choices and wanted to ask if 
someone could point us at an alternative or if we should just stick with 
the controlled studies.

Thanks again for the help,
