Intraocular pressure reduction (IOPR) from baseline comparing Limbus- with Fornix-based trabeculectomy.

Weighted mean differences (WMD) were computed by using a random effects model. 95% CI indicates 95% confidence interval; Limbus: Limbus-based conjunctival flaps group; Fornix: Fornix-based conjunctival flaps group; RCT: prospective randomized controlled trial; Retro: retrospective comparative study; Pro: prospective non-randomized comparative study.
