Design outcomes

Primary

MeasureTime frameDescription
Menstrual bleeding patterns as assessed by the Pictorial Bleeding Assessment Chart (PBAC)From enrollment to end of treatment at day 90.PBAC is one of the most common scoring systems used in the literature to quantify menstrual blood loss (MBL) using a pictorial scoring system, with a higher score representing a larger MBL and a score \>100 qualifying as heavy menstrual bleeding

Secondary

MeasureTime frameDescription
Menstrual distress questionnaire (MEDI-Q)From enrollment to end of treatment at day 90.The Menstrual distress questionnaire (MEDI-Q) is a valid and reliable instrument for the assessment of menstrual distress and its impact on psychological well-being. This tool can be utilized in research and clinical settings to comprehensively investigate the impact of menstruation on various populations
Endometrial thickness.On study day 90 +/- 14 days.Endometrial thickness measured by transabdominal pelvic ultrasound.
