Multistate-model stacked probability plots for ICU patients admitted a before or b after July 1. The plots illustrate the probability of being in each endpoint state—On-ECMO, In-ICU and weaned-off ECMO, Alive and out of ICU or dead—over the 90 days post-ECMO implantation. The respective probabilities and mean lengths of stay (with 95% confidence intervals) for each of these four states are reported in Additional file 2.
