Figure 2.

Summary box plots of a subset of blood parameters found to vary significantly by visited vs. non-visited sites. Both sexes differed in glucose (A) and uric acid concentrations (B). Males only differed in triglyceride (C) and cholesterol concentrations (D). Data were stratified by sex and visited site status. The dark horizontal bar represents the median, dashed vertical lines indicate variability outside the upper and lower quartiles, and outliers are indicated with open circles. The 95% confidence intervals about the mean (red circle) are displayed in red.
