metaprop excluding studies

[Agnelo Quadros]

Hello all,

I ran

metaprop OutcomeAa, TotalAa, random by(Study)

in Stata 17. It is showing the results but excludes 2 studies that have proportions of 0 and 1. How do I prevent Stata from excluding these studies (studies that have proportions of 0 and 1)?

Thank you.
