Knowledge on Periconceptional Use of Folic Acid in Women of British Columbia
Bibliographic record
Abstract
OBJECTIVE: Our purpose was to evaluate the knowledge of folic acid and its use preconceptionally in women of British Columbia. METHODS: The study was conducted at British Columbia Women's Hospital in Vancouver, Canada, between April 15 and June 15, 1999. Pregnant women and women in the postpartum period were asked to complete a survey on folic acid. RESULTS: In total, 1,004 women completed the questionnaire during the study period. Seventy-one percent of the women knew that vitamins could help prevent birth defects. Of those, 76.3% identified folic acid as the one vitamin specifically associated with reduction of birth defects. It was identified that 49.4% of all women took vitamins prior to pregnancy. CONCLUSIONS: Women in the population studied were relatively well informed about the benefits of folic acid, but less than 50% of them took vitamins prior to conception.

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.
