lower than those included for matching (34.5 vs. 52.7%, p < 0.001). Assuming that not the main text but Table 1 is correct, patients judged as "too severe" received ECMO more frequently and died less frequently.

In principle, prespecified protocols do not let us conduct arbitrary analyses after data collection. For this study, however, further analyses including the "too severe" patients will add remarkable value and meaning to the demonstrated results; ECMO could actually have more potential to save patients with severe COVID-19 than it was measured. The clinical benefit of ECMO initiation to severe COVID-19 patients, including those "too severe, " will be of significant interest to frontline providers.
