Figure 2 : Statistical power in case of moderate effect size heterogeneity: the statistical power at 0.05 significance level is calculated as the average of 1000 simulation runs.

Four values for the number of studies 5, 10, 20 and 30 were investigated. The calculation is based on moderate effect size heterogeneity, τ2 = 0.3. Two different effect size values 0 and 2 were considered.
