WebJul 9, 2024 · We used random-effect models to pool effect sizes (as opposed to fixed-effect models that operate on the assumption of a single true effect size). This approach is effective when the original ... WebWe see that the pooled effect size is RR \(=\) 2.02. The pooled effect is significant (\(p<\) 0.001), and indicates that suffering from depression doubles the mortality risk. We see that our estimate of the between-study heterogeneity variance is \(\tau^2 \approx\) 0.19. We would like to show you a description here but the site won’t allow us.
