Values are means ± SEM
Anthocyanins were not determined in urine collected from the placebo group
Symbols denote significant difference within treatment compared to fasting (0 h) values of morning spot urine samples, analyzed at week 0 and week 8 separately by ANOVA using the test parameter estimate for the main effect of time in our model (*P < 0.05)
