^aFSS is Functional Status Score;

^bMortality was modeled using Poisson regression with robust error estimates;

^cFSS among survivors was modeled using standard linear regression;

^dECMO is extracorporeal membrane oxygenation;

^eECPR is extracorporeal cardiopulmonary resuscitation;

^fLOS is length of stay
