  1. Data is reported as mean (SD), as median [q1, q3] or as number of events (proportion in %)
  2. N.B. SOFA is not reported because of excessive missing values
  3. Abbreviations: BMI Body mass index, SOFA Sequential Organ Function Assessment score
  4. a 22 missing values (12 in symptomatic and 8 in asymptomatic patients)
  5. b When no bilirubin was measured preoperatively, we imputated a value of 0 for the liver component of the SOFA score. 1 missing value in each subgroup
  6. c Urgency was defined by the need to undergo a surgery within 24 h
  7. d 12 missing values (8 in symptomatic and 4 in asymptomatic patients)
