We assessed age, gender, comorbidities (hypertension, diabetes, heart failure, obesity, BMI, chronic kidney disease, chronic obstructive pulmonary disease), ICU mortality scores (APACHE II, SAPS II), and admission laboratory results (C-reactive protein, procalcitonin, creatinine, albumin) using binomial logistic regression (Table 6). Here, ALB is linked to chronic obstructive pulmonary disease.
