Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment started in September, 2008 and continued through February, 2010 using neighborhood and city newspapers, posting of flyers, on-campus advertising and news features in campus, local and city newspapers and the local news. Eligible subjects reported to the Center for Pharmacy Care at Duquesne University for screenings and assessments.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Eligible subjects were randomly assigned using a computer-generated randomization scheme to receive either placebo or melatonin at a 3:1 ratio (treatment:placebo). Participants and principle investigators were completely blinded to the group assignments throughout the entire study thus achieving allocation concealment.

Reporting Groups
  Description
Sugar Pill Each capsule contained lactose and the study subjects took this nightly, p.o. for 6 months
Melatonin Each capsule contained 3 mg melatonin and each subject was asked to take this nightly p.o. for 6 months

Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Limitations to this study include small sample sizes, length of follow-up, and heterogeneity in terms of stage of perimenopause and prevalence of menopausal symptoms.
