Boxplot distribution of the ratio of 5-methyl-2’ deoxycytidine (5-mdC) to 2’-deoxyguanine (dG) (%5-mdC) levels by case-control status in each of twelve laboratory plates. The ends of the boxes are the 25^th and 75^th percentiles and the center line is the median. The lengths of the whiskers are defined as 1.5*(75^th percentile – 25^th percentile). The circles are values outside the whisker length
