  1. N nutritional group, C control group
  2. *No significant differences between C and N were observed in T0 values, while a significant difference was observed in T6 values (p<0.01) and in the T0–T6 change (p = 0.020)
  3. •A significant difference between N and C was observed in question 12 (p = 0.048) at T0
  4. °A significant difference between N and C was observed in question 4 (p = 0.008), in question 10 (p = 0.006), and in question 13 (p = 0.001) at T6
  5. ¶A significative difference between N and C was observed in the T0–T6 change of question 1 (p = 0.033), question 4 (p = 0.002), and question 12 (p = 0.004), while for question 2 it was almost significant (p = 0.052)
