Fluid Retention over the Menstrual Cycle: 1-Year Data from the Prospective Ovulation Cohort

Figure 1

Fluid retention scores (range: 0–4) in 62 initially ovulatory women across one year by menstrual cycle day relative to (a) the onset of menstrual flow ( , cycles per woman), where 0 is the first day of flow, and (b) in ovulatory cycles only ( , cycles per woman), where 0 is the first day of elevated basal temperature (denoted QBT rise) as estimated by the validated quantitative basal temperature algorithm (QBT). To correct for differences in the duration of data collection by women, data are presented as the average (bars ± standard error of the mean) of within-woman averages. Fluid retention was scored from 0–4 using the daily Menstrual Cycle Diary.
