Figure 2

In-hospital mortality: forest plot showing the pooled analysis of eight higher quality studies when the ECLS modality was VV-ECMO. The GenMatch data were used for the Pham and Noah studies, while the per-protocol analysis was used for the Peek study. Using a random-effects (RE) model: odds ratio (OR) = 0.96; 95% confidence interval (CI) = 0.52–1.77; I² = 82.95%; value for Q (PQ) < 0.001.
