Circadian variation of plasma melatonin during the follicular and luteal phases in PMDD women and controls.

Circadian variation of plasma melatonin during the follicular phase in PMDD women and an expanded group of controls.†
* indicates significant differences between controls and PMDD women (P<.05). Data are double-plotted for illustration purposes. Values are mean ± SEM. † This figure presents FP data from the 5 control participants and 5 PMDD participants included in Figure 1, but the control group is supplemented by data from 3 other young healthy women who were studied under constant conditions in unrelated experiments. This larger group of 8 controls was compared to the 5 PMDD women of the current study during the FP in an attempt to increase sample size and further confirm results from our baseline group comparisons.
