AUC results on simulated data for different number of studies using Pearson Correlations. Each row reports the results obtained on the data collections including 5, 10 and 50 studies, respectively. For each row the performances of each method are reported for level of systematic bias τ equal to 0.1, 0.5 and 1. All results are averaged over five different synthetic networks and different sample sizes (5, 20 and 50 samples). Standard deviations are indicated by the whiskers at the top of each plot. SD stands for Single-Dataset, while FEM, REM and FREM stand for Fixed, Random and FR-Effects method, respectively
