From: Variation of global DNA methylation levels with age and in autistic children
Variation of global DNA methylation in autistic children. The box plot shows methylation levels in healthy children (black) and autistic children (red). The horizontal line in each box indicates the median; the upper and lower bounds of the box represent the 75th and 25th percentiles, respectively; the upper and lower whiskers for each box mark the 95th and 5th percentiles, respectively; and the squares indicate the maximum and minimum values. Double asterisk indicates p < 0.001 for the pairwise comparison under the independent sample t test
