The multivariate logistic regression analysis was conducted by using the forward stepwise method, and the results showed that age > 60 years (odds ratio, OR = 6.78), NLR > 2.62 (OR = 3.862), transferrin < 200 mg/dL (OR = 4.222), PhA < 4.5° (OR = 7.478), and BFP < 10% (OR = 19.119) were risk factors for malnutrition in CKD patients (Table 6). Here, TF is linked to chronic kidney disease.
