Notes: Model 1 was not adjusted for any variables. Model 2 was adjusted for gender, age, and ethnicity. Model 3 was adjusted for hypertension, diabetes, asthma, pulmonary embolism, anemia, hematologic malignancy, connective tissue disease, myocardial infarction, peripheral vascular disease, liver disease, chronic kidney disease, malignancy, and sepsis. Model 4 was adjusted for heart rate, respiratory rate, systolic blood pressure, diastolic blood pressure, SpO2, white blood cell, platelet, potassium, sodium, glucose, creatinine, pH, PaCO2, anion gap, and bicarbonate. Model 5 was adjusted for age, gender, ethnicity, white blood cell, platelet, creatinine, hypertension, anemia, hematologic malignancy, connective tissue disease, peripheral vascular disease, myocardial infarction, liver disease, chronic kidney disease, sepsis, vasopressors, corticosteroids, intravenous fluids, red blood cell transfusions, SOFA, and SAPSII.
