Figure 4

Power in the meta-analysis in relation to the number of true-significant studies (we assumed a treatment effect) included in the meta-analysis. The dashed horizontal line indicates the power of all simulated meta-analyses together, which is equal to 80%. The triangles indicate the power in relation to the number of true-significant studies in the meta-analysis when all true-significant studies were large. The crosses show the power when all true-significant studies were small.
