Fig. 2

Coverage of sensitivity and specificity at the true optimal threshold (top panel). Bias of the optimal threshold (bottom panel). The Poisson distribution was chosen with λ=1.3 for the number of thresholds. The four plots at the bottom show the case of same standard deviations (SD), the top four plots the case of different standard deviations. The heterogeneity of the studies increases from left to right
