  1. Acute kidney injury is defined as serum creatinine ≥2 mg/dL or urine output <500 mL/day
  2. Shock is defined as vasopressor use or mean arterial pressure <60 mmHg for two measurements
  3. Abbreviations: ARDS acute respiratory distress syndrome, ICU intensive care unit; SOFA Sequential Organ Failure Assessment, CVP central venous pressure, RRT renal replacement therapy
  4. aData shown as n (%), mean (standard deviation) or median [inter-quartile range] if not normally distributed
  5. bp value for ICU type represents chi-square test for independence across ICU types
  6. cOf patients who received diuretics in 48–72 h after ARDS, 108 (93%) received furosemide
