In-hospital mortality: forest plot showing the subgroup pooled analysis of two RCTs and two quasi-RCTs 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 fixed-effects (FE) model: odds ratio (OR) = 0.51; 95% confidence interval (CI) = 0.38–0.69; I² = 12.22%; value for Q (PQ) = 0.33.
