From: Physical activity, black carbon exposure, and DNA methylation in the FOXP3 promoter
Non-active children with high BC on average have the highest FOXP3 promoter methylation (Kruskal-Wallis test). The short lines indicate individual observations, while the shaded areas indicated the distribution of the data for each respective group. The dotted lines indicate the mean percent methylation for all participants, and the thicker solid lines represent mean percent methylation for each respective group
