A survey of pregnant women using isotretinoin
Bibliographic record
Abstract
BACKGROUND: Isotretinoin is a known human teratogen, causing birth defects and/or subnormal cognitive performance in prenatally-exposed children. METHODS: A survey was conducted among women who called teratology information services throughout North America. Using a structured questionnaire, women with an isotretinoin-exposed pregnancy were prospectively interviewed before the outcome of the pregnancy was known. RESULTS: Almost 1/4 of the women surveyed (24%; 8/34) did not recall having contraception counseling before starting their medications. Once therapy was initiated, 62% (21/34) recalled using a birth control method, but only 29% (6/21) recalled using 2 forms of birth control, as specified by the voluntary pregnancy prevention programs. Monthly pregnancy tests were not always conducted during treatment, as recalled by the surveyed women (56%; 19/34). As many as 24% (8/34) of the women surveyed recalled that they were not screened using 2 pregnancy tests before receiving a prescription, another recommendation of the programs. Only a small number of the women (30%; 6/20) in the United States recalled being enrolled in any manufacturers' voluntary pregnancy prevention survey. CONCLUSIONS: Results demonstrate that essential components of voluntary pregnancy prevention programs were not consistently followed, which resulted in fetal exposures.

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.
