OR, odds ratio; 95% CI, 95% confidence interval.
BMI, body mass index; CHF, chronic heart failure; DM, diabetes mellitus; BE, base excess; AG, anion gap; SCr, serum creatinine; INR, international normalized ratio; SIRS, systemic inflammatory response system.
Adjusted for corresponding significant variables include age, sex, BMI, comorbidity (hypertension, chronic heart failure, chronic and kidney disease), blood gas results (pH value, base excess, anion gap, bicarbonate, and lactate), laboratory tests (white blood cell count, platelets count, hemoglobin, serum creatinine, and international normalized ratio), SOFA score, and SIRS score.
