Abstract

fetched live from OpenAlex

OBJECTIVE: To describe the effects of estetrol 15mg/drospirenone 3 mg on physical and emotional premenstrual and menstrual symptoms in a North American population. STUDY DESIGN: We used Menstrual Distress Questionnaire (MDQ) data from an open-label phase 3 trial conducted in the United States and Canada that enrolled participants 16-50 years to use estetrol/drospirenone for up to 13 cycles. Four most bothersome MDQ domains were evaluated: the physical domains of Pain and Water Retention and the emotional domains of Negative Affect and Impaired concentration. We assessed mean changes from baseline to end of treatment in premenstrual and menstrual scores in starters and switchers (use of hormonal contraception in prior 3 months) and performed a shift analysis on individual symptoms within each domain. RESULTS: Of 1864 treated participants, 1308 (70.2%) completed both MDQs of which 676 (51.7%) were starters and 1179 (90.1%) were US participants. Starters reported significant improvements (p < 0.05) for menstrual Pain (-3.3), premenstrual (-1.5) and menstrual (-2.0) Water Retention and premenstrual Negative Affect (-1.2). Switchers reported no significant changes in any of the four domains. We observed a decrease in symptom intensity in >40% of participants within the domain Pain for Headache, Cramps, Backache, Fatigue, and General Aches and Pain; within the domain Water Retention for Weight Gain, Skin Blemish, Painful or Tender Breast, and Swelling; and within the domain Negative Affect for Anxiety, Mood Swings, and Irritability. CONCLUSION: Estetrol/drospirenone starters experienced the most significant improvements in the MDQ domains Pain, Water Retention, and Negative Affect. Domain scores for switchers remained stable. IMPLICATIONS: In first time pill users, the estetrol/drospirenone containing oral contraceptive significantly reduces menstrual pain, premenstrual and menstrual water retention and premenstrual negative affect. In those switching from another pill, the menstrual-related distress symptoms remain stable.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
