Abstract
Madsen K, Hviid A, Vestergaard M et al. A population-based study if measles, mumps, and rubella vaccination and autism. N Eng J Med2002 Nov; 347 : 1477 –82 [OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] QUESTION: Is the combined measles, mumps and rubella (MMR) vaccination associated with autism? Retrospective population study of all children born in Denmark between January 1991 and December 1998. 537,303 children were born during the study period; 49% girls. 82% received the MMR vaccine. The Danish Civil Registration System assigns a unique identification number to every live birth and new resident in Denmark. MMR vaccination status was obtained from the Danish National Board of Health.

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.
