... assuming a common between-study variance tau2 across subgroups. The 
default in metaprop() of meta is to allow different between-study 
variances (analogous to RevMan 5, the software for Cochrane Reviews). 
However, this can be changed using argument 'tau.common = TRUE' in 
metaprop().

As stated by Ty, metaprop() does not allow to specify the weights at the 
moment. I put this on my TODO list.

Best wishes,
Guido
