Proportion of correct conclusion obtained with the four methods as the function of the true mean effect sizes. Each boxplot describes the distribution of results across different scenarios. Red dashed lines indicate the proportions 0.75 and 0.9. Values of p indicate the significance of the relationship between the proportion of correct conclusion and the true mean effect. The proportion of correct conclusion PCC assesses the ability of the methods to determine the true direction of the effect of the tested intervention relatively to the comparator
