OR: odds ratio; CI: confidence interval. Models were derived from logistic multivariate regression models. The crude model was adjusted for none. The Adjust I model was adjusted for age, gender, and ethnicity. The Adjust II model was adjusted for age, gender, ethnicity, congestive heart failure, cardiac arrhythmias, valvular disease, hypertension, uncomplicated diabetes, complicated diabetes, renal failure, liver disease, metastatic cancer, coagulopathy, alcohol abuse, drug abuse, anion gap, bicarbonate, glucose, creatinine, chloride, hemoglobin, lactate, platelet, potassium, APTT, PT, sodium, BUN, WBC, heart rate, systolic blood pressure, respiratory rate, temperature, SPO2, ICU length of stay, SAPSII, and SOFA.
