  1. Model I, linear analysis; Model II, non-linear analysis. Adjusted for age, Gender, ethnicity, hospital discharge year, CHF, Diabetes, Metastatic cancer, Hepatic failure, Sepsis, Immunosuppression, BMI, Hemoglobin, Albumin, BUN, serum creatinine, and SOFA score. CI confidence interval, OR odds ratio. *P < 0.05 indicates that model II is significantly different from Model I.
