415 The Importance of Proper Placebo-Control in Sexual Medicine Medical Device Trials
Bibliographic record
Abstract
To evaluate the placebo effect for a medical device that uses monopolar radiofrequency (RF) with cooling when treating women experiencing symptoms of sexual dysfunction and to assess the importance of inclusion of an appropriate placebo control in clinical trials for women’s health. A prospective, longitudinal, randomized, blinded, placebo-controlled, multi-center clinical study was conducted for the treatment of sexual dysfunction with vaginal introital laxity as a primary symptom. The treatment is an outpatient monopolar RF procedure that couples energy administration to heat underlying tissue while cooling and protecting the vaginal mucosa. Efficacy and safety have been published elsewhere. This international study is the first and only of its kind ever done for RF treatment for sexual dysfunction. Subjects were randomized in a 2:1 ratio to either the active (90 J/cm2) or sham (≤1 J/cm2) treatment groups. Nine sites were chosen in multiple countries (Italy, Spain, Canada and Japan). Subjects were followed up at 72 hrs., 10 days, and 1, 2, 3, and 6 months post-treatment. Patient reported outcomes included the Female Sexual Function Index (FSFI) and a 7-point Likert scale assessment for vaginal laxity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
