1
CRP, C-reactive protein.
2
Values are arithmetic means ± SEs from samples collected before the dietary intervention (preintervention values).
3
Values are least-squares means ± SEs (adjusted for the baseline values) from a linear mixed-model ANOVA that included covariates of age, baseline (preintervention values), BMI, and weight.
4
Values are for the blueberry and placebo comparison at 8 wk.
5
n = 17, blueberry lipid-lowering medication users; n = 23, placebo lipid-lowering medication users.
