Abstract
BACKGROUND: The synthetic androgen Danazol, was developed in the 1970's as a treatment for endometriosis. Its use was soon advocated in women with unexplained subfertility. Two randomised trials were subsequently conducted to assess the effectiveness of danazol in this population. OBJECTIVES: The objective of this review was to assess the effect of danazol on live birth rate in women with unexplained subfertility. SEARCH STRATEGY: We searched the Cochrane Menstrual Disorders and Sub-fertility Group's specialised register of trials (searched November , 2006) the Cochrane Register of Controlled Trials (The Cochrane Library, Issue 4, 2006), MEDLINE (1966-November 2006), EMBASE (1980 - November 2006) and reference lists of articles. SELECTION CRITERIA: Randomised trials of danazol compared with placebo or no treatment in women with unexplained subfertility. DATA COLLECTION AND ANALYSIS: Data were extracted by two reviewers EH and GT. MAIN RESULTS: Two trials involving seventy-one women were included. There was no statistically significant difference in the live birth/ ongoing pregnancy rate between danazol and placebo at the end of treatment (OR 1.16, 95% CI 0.0 to 8.29; P=0.36) or at the end of follow-up (OR 2.41; 95% CI 0.59, 9.82; P=0.22). There was no significant difference in clinical pregnancies following treatment (OR 0.14, 95% CI 0.01, 2.26; P=0.17), however there were significantly more clinical pregnancies during the follow-up period in the danazol group compared with the placebo group (OR 3.15, 95%CI 0.98, 10.10; P<0.05). Multiple side effects were reported. AUTHORS' CONCLUSIONS: Available data demonstrate no evidence of the benefit of danazol for unexplained subfertility. Although there is insufficient evidence to be certain of this, the need for contraception during treatment and the adverse effects and costs of danazol, make its use for this problem unwarranted. The increased pregnancy rate in the long term follow-up data may be attributable to additional therapies and did not influence the live birth/ongoing pregnancy data.

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.
