Circadian melatonin profile during the follicular phase in PMDD women and an expanded group of controls.†

PMDD: premenstrual dysphoric disorder; FP: follicular phase; DLMOn: dim light melatonin onset; DLMOff: dim light melatonin offset; AUC: area under the curve values are mean ± SEM.†This table presents FP data from the 5 control participants and 5 PMDD participants included in Table 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.
