OR, odds ratio; CI, confidence interval
Model 1: Unadjusted model
Model 2: Adjusted for age, sex, ethnicity, cerebrovascular disease, renal disease, the Charlson comorbidity index, the SOFA score, the SAPSII score and septic shock
Model 3: Adjusted for variables included in Model 2 + SBP, heart rate, respiratory rate, temperature and SpO2
Model 4: Adjusted for variables included in Model 3 + white blood cell count, hemoglobin, platelet count, anion gap, bicarbonate, calcium, blood urea nitrogen, sodium, potassium, prothrombin time, glucose, β-blockers, diuretics, lipid-lowering drugs and ACEIs
