HR: hazard ratio; CI: confidence interval; a Model 1 was adjusted for demographic information, including age, gender, marital status, and ethnicity; b Model 2 also adjusted for complications including congestive heart failure, hypertension, and diabetes; c Model 3 additionally adjusted laboratory tests, including albumin, bicarbonate, anion gap, creatinine, bilirubin, chloride, glucose, hematocrit, hemoglobin, sodium, potassium, blood urea nitrogen, white blood cell, lactate, prothrombin time, international normalized ratio, lymphocyte, and neutrophil; d Model 4 made additional adjustments to clinical treatment, including renal replacement therapy, mechanical ventilation, and vasopressor use; e Model 5 additionally adjusted the scoring system, including sequential organ failure assessment and simplified acute physiology score II.
