AP-values from an ANOVA testing for differences in means by milk consumption type (or from Chi-square test for differences in frequency by milk consumption type if variable is categorical).
Data is expressed as Mean (SD) or Bfrequency by milk consumption type if variable is categorical.
BB = Human milk directly from breast only (No formula)
BP = Human milk from a bottle (No formula)
TF = Traditional formula
ASF = Lactose-reduced formula with added corn syrup solids
