Figure 2

Comparison of scores of concentration of urinary polyphenol biomarkers according to the presence of (a) polyphenol-rich diet or (b) overweight/obesity. . Data are depicted by box plots extending from the 25th to the 75th percentile and whiskers ranging from the lower limit to the upper limit. The horizontal line in the box plot represents the median. The score of total 22 polyphenol biomarkers was computed by the summary of the score of each polyphenol biomarker/22.
