  1. * Significantly correlations exist when p < 0.05
  2. aProtein intake = protein (g) per day)
  3. bEnergy intake = energy (kcal) per day
  4. cProtein intake = protein (g) per kg body weight per day
  5. dEnergy intake = energy (kcal) per kg body weight per day
  6. eCorrelations were tested by using the Pearson test
