  • Models I and II were derived from Cox proportional hazards regression models: model I covariates were adjusted for age; gender; ethnicity; model II covariates were adjusted for age; gender; ethnicity; heart rate; SBP; DBP; respiratory rate; SPO2; anion gap; serum bicarbonate; serum potassium; SCr; BUN; haematocrit; platelet count; WBC count; PTT; PT; INR; stroke; pneumonia; COPD; chronic liver disease; chronic renal disease; RRT; malignancy; vasoactive agent; SOFA; SAPSII.

  • BUN, blod urea nitrogen; COPD, chronic obstructive pulmonary disease; CS, cardiogenic shock; ; DBP, diastolic blood pressure ; INR, international normalised ratio; NAR, neutrophil-to-albumin ratio; PT, prothrombin time; PTT, partial thromboplastin time; RRT, renal replacement therapy; SAPSII, Simplified Acute Physiology Score ; SBP, systolic blood pressure ; SCr, serum creatinine; SOFA, Sequential Organ Failure Assessment; SPO2, percutaneous oxygen saturation.
