Subject Population ()
The characteristics and demographics for the subjects in the intervention and control groups were similar and are summarized in Table 1. Although the number of male and female athletes recruited for the study was comparable, 542 (68.3%) of the subjects who ultimately enrolled were girls. This finding did not affect the analysis, however, because the percentage of girls in the intervention and control groups (69.9% vs 66.8%) was similar.
