Global DNA methylation box plots. For each group, the bottom and top bars indicate the 10th and 90th percentiles, respectively. The bottom and top of each box indicate the 25th and 75th percentiles, the line through the middle of each box represents the median, and the mean value for each group is noted by (+) in each box. Thirty GC genomic DNA from controls and 39 GC genomic DNA from PCOS women were analyzed. P value is determined by Mann-Whitney U test. *, P < 0.05, compared with the controls
