Abstract
Abstract A number of arthritic conditions may occur in patients with psoriasis, and these must be differentiated from psoriatic arthritis. Since psoriasis is a common condition, occurring in 2–3% of the population, and rheumatoid arthritis, the most common form of inflammatory arthritis, may occur in 1% of the population, the co-occurrence of rheumatoid arthritis and psoriasis would be expected by chance alone in 1 in 10 000 people. Since rheumatoid arthritis, like psoriatic arthritis, is inflammatory in nature, the differentiation may be difficult. Osteoarthritis, which is the most common form of arthritis, occurs in about 5% of the population and it may co-exist with psoriasis. While osteoarthritis is not usually an inflammatory form of arthritis, it does affect the end joints of the fingers, a site commonly affected in patients with psoriatic arthritis, and therefore one needs to differentiate osteoarthritis from psoriatic arthritis. Psoriatic arthritis may sometimes be misdiagnosed as gout. Gout is a crystal-induced arthritis caused by uric acid deposition in the joints.

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.
