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