Thirty-day in-hospital mortality of the overall cohort and patients with prior CPR according to annualized hospital volume of VA-ECMO procedures. *p < 0.001: total cohort vs. prior CPR in each category (overall, ≤ 50, > 50–100, > 100). +p < 0.05: ≤ 50 vs. > 50–100, ≤ 50 vs. > 100, > 50–100 vs. > 100 for the total cohort and prior CPR
