  1. Reference (ref) for all models was no AKI or AKI stage 1
  2. Model 1: univariable model
  3. Model 2: adjusted by sex, SOFA score, and Charlson score
  4. Model 3: adjusted by model 2 + candidate variables age, BMI, days of mechanical ventilation, receipt of NMB, receipt of vasopressor/inotrope, hospital LOS, receipt of ECMO according to multivariable p-value ≤0.05. Final models included the addition of receipt of NMB (model of 6MWD) and days of mechanical ventilation (model of return to driving)
  5. a Data are presented as beta coefficient and 95% confidence intervals
  6. b Data are presented as odds ratios and 95% confidence intervals
