Comparison of radiological severity in psoriatic arthritis and rheumatoid arthritis.
Bibliographic record
Abstract
OBJECTIVE: To compare the radiological severity of patients with psoriatic arthritis (PsA) and rheumatoid arthritis (RA). METHODS: Patients were identified from the University of Toronto PsA and RA databases. Using the earliest available radiographs, each RA patient was matched to a single PsA patient on the basis of sex, age, and disease duration. Two rheumatologists blinded to the patient's diagnosis scored the radiographs using the modified Steinbrocker method. RESULTS: PsA and RA groups were similar with respect to demographics as well as the use of disease modifying antirheumatic medications. No significant difference in Steinbrocker score for the hands and feet or the hands only was noted. Patients with RA had a higher radiological score in the feet. The 2 groups were similar in the number of joints with significant radiological damage (Steinbrocker 3 and 4). CONCLUSION; Overall the radiological severity in the hands and feet of patients with PsA was comparable to that of patients with RA.

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.
