They are (1) the crude model (unadjusted), model I (adjusted for age, heart rate, MBP, respiratory rate, temperature, SpO2, and glucose), model II (adjusted for model I + diabetes, chronic pulmonary disease, liver disease, renal disease, platelets, hematocrit, BUN, calcium, creatinine, and potassium), and model III (adjusted for model II + INR, PT, ALT, AST, CKMB, SOFA, lactate, epinephrine, dopamine, and vasopressin).
