Mean daily consumption (mg/day) of anthocyanin compounds in the background diet for the blueberry- and placebo- treated groups calculated from diet diaries obtained during the week before enrollment (baseline), week 8 of the intervention (interim), and during the final week of the intervention. Separate repeated measures analyses for each anthocyanin compound indicated main effects for time for cyanidin (p = 0.01), malvidin (p = 0.05), peonidin (p = 0.05), and a trend for time for petunidin (p = 0.08). However, there was no group by time interaction that would indicate a betweem-group difference in such consumption outside the intervention.
