TABLE 2.

Approximate values of relative residual heterogeneity (I²) for each combination of simulation parameters pertaining to the mean within-study sample size (E[N]) and residual heterogeneity ( $τ_{ϵ}^{2}$ )

	$τ_{ϵ}^{2} = 0.0025$	$τ_{ϵ}^{2} = 0.01$	$τ_{ϵ}^{2} = 0.04$	$τ_{ϵ}^{2} = 0.25$	$τ_{ϵ}^{2} = 0.64$
E[N] = 100	0.06	0.20	0.50	0.86	0.94
E[N] = 850	0.25	0.68	0.89	0.98	0.99
