The significance of the differences between the groups was assessed with a t-test for age, a Mann–Whitney test for the duration of ECMO, and a Fisher exact test for all the other variables.
ECMO, Extracorporeal membrane oxygenation; ARDS, Adult respiratory distress syndrome; CVA, Cerebrovascular accidents; MSOF, Multisystem organ failure
*
Data are presented as mean±SD for age, as median (25–75%) for the duration of ECMO, and as number (%) for all the other variables.
