Data patterns in the simulations for standardized mean difference (SMD)

SMD	Equal study sizes	Unequal study sizes	Full results in
			Bakbergenuly et al34
			Appendices:
K (number of studies)	5, 10, 30	5, 10, 30
n or $\overline{n}$ (average (individual) study size—total of the two arms)	20, 40, 100, 250	30 (12, 16, 18, 20, 84),
	30, 50, 60, 70	60 (24, 32, 36, 40, 168),
For K=10 and K=30, the same set of unequal study sizes		100 (64, 72, 76, 80, 208),
is used twice or six times, respectively		160 (124, 132, 136, 140, 268)
q (proportion of each study in the control arm)	1/2, 3/4	1/2, 3/4
δ (true value of the SMD)	0, 0.2, 0.5, 1, 2	0, 0.2, 0.5, 1, 2	B1, B2
τ 2 (variance of random effect)	0(0.5)2.5	0(0.5)2.5	A1, A2
