Lactate levels, lactate clearance-1 at specific time points and lactate clearance-2 were compared

Subgroups (The survivors versus Non-the survivors) refer to 30-day mortality. p-values calculated for comparison of the survivors versus non-the survivors by statistical analysis

Data are mean ± SD or n (%)

^*Determined by Mann-Whitney U test or Spearman’s rho test

Abbreviations: ECMO extracorporeal membrane oxygenation, LL lactate level at specific time, LC-1 lactate clearance at specific time, LC-2 the duration between ECMO implantation time and time point that Lactate cleared more than 10% of the initial level
