Figure 1From: Estimating required information size by quantifying diversity in random-effects model meta-analyses Diversity ( D 2 ) compared to inconsistency ( I 2 ) in 10,000 simulations of meta-analyses with number of trials included k = 6. Odds ratio = 1.00 and proportion of events in control group PC = 0.30. Meta-analyses depicted as open circles. D 2 nears asymptotically to I 2 when heterogeneity nears 0% or 100%. Line of unity, D 2 = I 2 black line.Back to article page
