Hello, I am conducting a meta analysis which involves 27 prevalence studies. As I have a I square that greatly exceeds 50% I was wondering whether the Trim and Fill method would indeed be adequate to adjust for publication bias in this case. If not, would there be any other non parametric method I could use instead ( and if so, can it be calculated using STATA).
I would be most appreciative if you could guide me.
Thanking you in advance,
