Assessment of the threshold effect in all accuracy studies

Weighted regression (inverse variance) | ||||
| Variable | Coefficient | SE | t | P value |
| a | 3.643 | 0.548 | 6.652 | 0.0000 |
| b(1) | -0.239 | 0.314 | 0.760 | 0.4617 |
τ2 = 2.3703 (convergence is achieved after five iterations); Restricted Maximum Likelihood estimation (REML). n = 14; Filter OFF; Add 0.5 to all cells of the studies with zero. Spearman correlation coefficient: -0.266, P = 0.358; Logit (true positive rate) vs Logit (false positive rate); Moses’ model (D = a + bS).
