FIGURE 1—

Prevalence of any vasomotor symptoms (a) and vasomotor symptoms reported for 6 or more days (b) in the preceding 2 weeks, by participants’ menopausal transition status and race/ethnicity: Study of Women’s Health Across the Nation, 1996–2002. …Note. VMS = vasomotor symptoms. Prevalence was computed at the first visit at which a change in menopausal status was observed; women could thus contribute only one observation to each menopausal transition status category but could contribute more than one observation by progressing to different categories over the 5-year follow-up. Thus, observations in the 4 menopausal transition status categories were not mutually exclusive.
