Folate and Clefts of the Lip and Palate—A U.K.-Based Case-Control Study: Part I: Dietary and Supplemental Folate
Bibliographic record
Abstract
OBJECTIVES: We sought to determine the associations between nonsyndromic cleft lip with or without cleft palate (CL-P) and cleft palate only (CP) and maternal intake of dietary folate and supplemental folic acid, in an area where the prevalence at birth of neural tube defects has been high and flour is not fortified with folic acid. METHODS: Interviews regarding periconceptional dietary intake and supplement use were completed with the mothers of 112 CL-P cases, 78 CP cases, and 248 unaffected infants. The data were analyzed by logistic regression methods. RESULTS: There was no overall association between CL-P and CP and either energy-adjusted total folate intake or supplemental folic acid use, irrespective of dosage. CONCLUSION: Overall, higher intakes of total folate do not appear to prevent oral clefts in this population.

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.
