Criteria	Studies (Effects)	Estimate [SE]	95% CI	$\hat{τ}$	I²
All studies	79 (223)	0.274 [0.036]	[0.201, 0.346]	0.242	73%
Low ROB outcome reporting	61 (185)	0.284 [0.042]	[0.199, 0.368]	0.249	75%
Low ROB sequence generation	31 (79)	0.218 [0.059]	[0.098, 0.340]	0.262	76%
Low ROB allocation concealment	17 (37)	0.320 [0.078]	[0.153, 0.487]	0.255	76%
Low overall attrition	11 (23)	0.244 [0.070]	[0.084, 0.404]	0.148	57%
