  1. Abbreviations: MTHFR methylenetetrahydrofolate reductase
  2. a NPC/N ratio of non-protein energy per nitroden
  3. All values are median (25th and 75th percentiles)
  4. The normality of the data was first assessed using the Shapiro-Wilks test
  5. The values are compared between the groups by Kruskal-Wallis test and Bonferroni's multiple comparison test as appropriate. *p < 0.05
  6. b-cMultiple comparison; A different alphabet shows that there is a significant difference
