  1. a Defined in terms of solid food only.
  2. b Results from PROC MIXED indicate no differences in volume of food consumed over time by quartile of change in energy density from 0 to 18 months and no difference in grams of food consumed across quartiles at baseline.
  3. c Results from PROC MIXED indicate significant differences (p < 0.0001) for change in kcals consumed over time by quartile of change in energy density from 0 to 18 months and a significant difference (p < 0.0001) in kcals consumed across quartiles at baseline.
