Anti-Jo1 Antibody in Polymyositis/dermatomyositis Is Still Closely Associated with Lung rather than Joints
Bibliographic record
Abstract
To the Editor: We read with interest the paper by Klein, et al 1 containing detailed data about arthritis in patients with idiopathic inflammatory myopathy (IIM). The authors reported that arthritis was a common feature of IIM that appeared not only at the onset of disease, but also might precede muscular manifestation and occur at any time. Especially noteworthy, 27 out of 29 anti-Jo1–positive patients (93.1%) had arthritis, and this finding led authors to confirm a strong association between arthritis and anti-Jo1. Traditionally, anti-Jo1 is known to be associated with interstitial pulmonary disease and polymyositis (PM)/dermatomyositis (DM), often manifesting the pulmonary symptom. It had occasionally been reported in arthritis in patients with PM/DM, but there were not enough occurrences to treat the relationship with anti-Jo1. In that context, the authors’ 93.1% was an exceptional result considerably distinguished from previous data. We investigated … Address correspondence to Dr. T.Y.

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; both teacher heads agree on what is shown here.
