Random-effects model and heterogeneity statistics for IOPR (%).

Random-effects model (k = 8)
	Estimate	se	Z	P	CI lower bound	CI upper bound
Intercept	0.324	0.255	1.27	.244	−0.278	0.926

Heterogeneity statistics
Tau	Tau2	I2	H2	R2	df	Q	P
0.620	0.384 (SE = 0.2572)	80.66%	5.170	.	7.000	30.026	<.001

Tau² estimator: restricted maximum-likelihood. Knapp and Hartung (2003) adjustment used.

CI = confidence interval, IOPR% = intraocular pressure reduction percentage.
