Power of the test for inconsistency aggregated over sample size and number of trials

	Heterogeneity				No heterogeneity
	IF = 0.3	IF = 0.45	IF = 0.6	IF = 1	IF = 0.3	IF = 0.45	IF = 0.6	IF = 1
	Frequent Events
IVDL	0.17	0.26	0.36	0.59	0.20	0.38	0.52	0.77
KHDL	0.19	0.27	0.37	0.60	0.27	0.44	0.58	0.80
	Rare Events
IVDL	0.10	0.15	0.21	0.38	0.09	0.16	0.25	0.49
KHDL	0.13	0.18	0.24	0.41	0.16	0.23	0.33	0.55

Results are presented for equal number of trials across comparisons. IF: inconsistency factor, IVDL: inverse variance method with the DerSimonian and Laird estimator, KHDL: the Knapp-Hartung method with the DerSimonian and Laird estimator.
