¹ The subjects were classified into 2 groups according to low-protein diet in all subjects
² The data are presented as means ± standard deviations
³T-test was performed to compare parameters according to low-protein diet
⁴ The data are presented as number (percentage)
⁵ Malnourished patients were assessed using modified SGA (subjective global assessment)
⁶ Chi-square test was performed to compare the categorical parameters (malnutrition) according to low-protein diet
