Validation of the proposed ILAR classification criteria for juvenile idiopathic arthritis. International League of Associations for Rheumatology.
Bibliographic record
Abstract
OBJECTIVE: The new International League of Associations for Rheumatology (ILAR) classification criteria were proposed to facilitate communication among pediatric rheumatologists. Before they are applied in daily practice they should be clinically validated. METHODS: We retrospectively applied the proposed criteria on our pediatric rheumatology patient population seen between June 1 and August 31, 1998. RESULTS: We saw 67 patients with oligoarticular (oJRA), 6 with polyarticular/RF negative (pJRA), and 8 with systemic juvenile rheumatoid arthritis (sJRA), all classified according to American College of Rheumatology criteria, 5 with juvenile psoriatic arthritis (PsA) according to the Vancouver criteria, and 11 with juvenile spondyloarthritis (SP) according to the European Spondylarthropathy Study Group preliminary criteria. Of the 97 patients, 85 could be clearly classified according to the ILAR criteria. Twelve patients (12%) were classified as "other." Six patients could not be classified as "oligo" because of a family history of psoriasis, and did not fulfill the criteria for PsA either. All 6 "other" patients fulfilled criteria for 2 different categories. CONCLUSION: With this ILAR proposed classification criteria 88% of patients could be classified. In patients classified as "other," the psoriatic trait caused the most difficulty in classification.

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.
