DRI dietary reference intake

^aDietary reference met based on reported 3-day diet record analysis. Laboratory reference met based on measurements from Quest Diagnostics, assessed as above minimum level

^bMissing values not reported

^cNo statistically significant difference between no. meeting DRI guidelines at start vs. endpoint, by Fisher’s exact test, p = 0.05

^d7 missing values for laboratory folate at baseline due to laboratory error
