Menopause and Possible Effect on Association Between Age and Anticyclic Citrullinated Peptide Antibodies in Women At Risk of Rheumatoid Arthritis
Bibliographic record
Abstract
To the Editor: We read with interest the article by Berens, et al 1 reporting that increasing age was associated with positivity for anticyclic citrullinated peptide antibodies (anti-CCP) 3.1 and anti-CCP–IgA in individuals at risk of rheumatoid arthritis (RA), that is, first-degree relatives (FDR) of patients with RA. We found similar results in a Swiss cohort of FDR: anticitrullinated protein antibodies (ACPA) positivity, particularly anti-CCP3.1, was associated with older age2. However, in contrast to Berens, et al 1, we found a peak in prevalence in the age group of 45 to 55 … Address correspondence to Dr. D.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
