^aEstimated by logistic regression in 462 subjects with complete information, adjusted for all other variables in the table.

^bDefined as systolic blood pressure <90 mmHg and/or treatment with vasopressors.

^cDefined as any lactate >3.2 mmol/l or base excess ⩽−5 (in patients without chronic kidney failure).

^dDefined as either kidney dysfunction (increase >45 µmol/l in S-creatinine in patients without chronic kidney dysfunction or CRRT or dialysis treatment), liver dysfunction (S-bilirubin >45 mmol/l in patients without chronic liver disease or diagnosis of acute pancreatitis, cholecystitis or cholangitis), hypoxemia (oxygen saturation <87% or <79% if pneumonia or mechanical ventilation); altered mental status; coagulation dysfunction (INR>1.5 or APTT>60 s in patients without warfarin or heparin treatment).
