Abstract
Women who use oral contraceptives just prior to conception may be more likely than nonusers to experience adverse birth outcomes according to a study of health records from the Canadian province of Saskatchewan.1 Those who used the pill within 30 days of their last menstrual period had elevated odds of preterm birth and low birth weight conditions that are associated with infant morbidity and mortality. The researchers examined records from Saskatchewan Health Databases which contain information on 99% of the provinces residents. They obtained data on physician services hospital stays and prescription drug use in the year prior to giving birth for a random sample of 50% of women who had a pregnancy between 1997 and 2000. these outcomes. In an analysis that adjusted for womens socioeconomic and chronic disease status pill use within 30 days of the last menstrual period was positively associated with the occurrence of very low and low birth weight (odds ratios 3.2 and 1.9 respectively) and preterm delivery (1.6). Use 2-3 months prior to the last menstrual period was not associated with adverse birth outcomes. (excerpt)

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 it
