Review: the Prentif cervical cap was as effective as the diaphragm in preventing pregnancy, and the FemCap was not
Bibliographic record
Abstract
(2002) Cochrane Database Syst Rev 4, CD003551. Gallo MF, Grimes DA, Schulz KF. . Cervical cap versus diaphragm for contraception. . ;( . ): . (latest version 22 Aug 2002) . QUESTION: Is the cervical cap more effective, safe, and acceptable than the diaphragm for contraception? Studies were identified by searching Medline, Popline, Cochrane Controlled Trials Register, EMBASE/Excerpta Medica, and LILACS; reviewing the references of pertinent articles; and contacting manufacturers and investigators in the field. Studies were selected if they were randomised controlled trials in any language comparing a cervical cap with a diaphragm in women of reproductive age with no contraindications to either barrier method. 2 reviewers independently extracted data on study quality (design, blinding, randomisation method, allocation concealment, follow up, and discontinuation rates), participant characteristics, type of cervical cap and diaphragm, and results. Extracted data were verified by a second reviewer. Outcomes were contraceptive efficacy, discontinuation, safety, and acceptability. 2 trials met the selection criteria: 1 trial compared the Prentif Cavity Rim Cervical Cap (Lamberts Ltd, Oxford, UK) with the Ortho diaphragm (Ortho Pharmaceutical Corporation, Raritan, NJ, USA) (n=1529, 6–24 mo follow …

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.
