Data are probability (%; 95% CI) or mean (95% CI). Probabilities do not add up to 100 due to rounding. Probabilities calculated at each timepoint for the whole population of 83 patients, with right-censoring of patients who did not reach the final absorbing state at later timepoints. ECMO=extracorporeal membrane oxygenation. ICU=intensive care unit.

^*Probability of being in each endpoint state at the defined day after ECMO initiation.

^†Mean number of days spent in each endpoint state on the indicated day after ECMO initiation.
