Circulating glucuronic acid predicts healthspan and longevity in humans and mice

Figure 2. Variation of glucuronic acid levels with age. The relationship between chronological age and glucuronic acid levels in (A) the Estonian Biobank secondary cohort, (B) the Estonian Biobank primary (discovery) cohort, and (C) the Framingham Offspring cohort. In each case, the best-fit regression line through the data is shown, with the 95% confidence interval for this line shaded in grey. Glucuronic acid concentrations are represented as standard deviations of normalized concentrations within each dataset.
