Age at menarche in women with PCOS (gray boxes) and controls (white boxes) as a function of reported weight group at ages 10 to 14 years. The line represents the median, boxes the 25^th and 75^th percent confidence limits and the black dots the age at menarche for outliers. The age at menarche was later in women with PCOS and controls whose weight was less than their peers (a vs. b; p<0.001) and lower in those whose weight was more than their peers (c vs. b; p<0.001) than in the group with a similar weight to that of their peers.
