Correction to: Extracorporeal membrane oxygenation for COVID-19: a systematic review and meta-analysis (Critical Care, (2021), 25, 1, (211), 10.1186/s13054-021-03634-1)

Abstract

Following publication of the original article [1], the authors identified errors in Tables 1, 2, the Additional file 2: Figure S1 and Additional file 3: Figure S2. The correct Tables are is given hereafter and an explanation on the Additional file Figure S1 and Figure S2. Table 1 currently reads: Takeda et al. had 237 number of patients. Table 1 should read: Takeda et al. had 370 patients ; 81.4% (301 patients) were males and 343 required VV ECMO. Table 2 currently reads Takeda et al. reported mortality in 67 patients. Table 2 should read as Takeda et al. reported mortality in 120 patients with mean duration of 18.4 ± 15.2 days on ECMO. The authors want to note that the forrest plot calculations in Fig. 2 was based on 370 patients. The article was written based on the forrest plot results (Fig. 2), which is the correct version. The supplementary Figures 1 and 2 represent subgroup analysis based on 237 patients. However, on reanalysis, the final analysis results mostly remained the same, except for the confidence intervals, we have explained this in great detail in our rebuttal letter to Hoechter et al. [2]. The mortality on VV ECMO was 35.7% (95% CI: 30.8-40.7) while the regional mortality in Asia was 43.3% (95% CI: 28.9-58.3%). All the changes that were requested are implemented in this correction and the original article [1] has been corrected. © The Author(s) 2021
