Figure 2.

Pre- and postmenopausal classification of study participants. Study participants were categorized as premenopausal or postmenopausal based on the calculated menopause age of 46.6 years (broken line). Seventy-one (71) participants corresponding to 2.36% overall were within the 45–46.6-year group. The number of participants within each age group is shown in Table 1. Percentages shown for each age group were calculated as a fraction of participants within that group over the total participants recruited.
