OR: odds ratio; CI: confidence interval. Models were derived from logistic regression models. Nonadjusted model adjusting for none. Adjusted model I adjusting for age, ethnicity, and gender. Adjusted model II adjusting for congestive heart failure, arrhythmia, age, ethnicity, gender, diabetes, hypertension, renal failure, metastatic cancer, solid tumor, coagulopathy, obesity, electrolyte disorder, hemorrhagic anemia, anion gap, bicarbonate, creatinine, chloride, hematocrit, platelet, potassium, APTT, INR, PT, BUN, SAPSII, SOFA, heart rate, systolic blood pressure, diastolic blood pressure, respiration rate, temperature, SpO₂, and white blood cell count.
