Symptoms affect a person's ability to perform basic activities of daily living, including eating, cooking, and dressing, as well as more complex occupational and recreational tasks. No therapies modify or arrest the progression of damage to cartilage and bone. Hence, treatment of hand osteoarthritis is focused on symptom relief (2). Patients with symptomatic hand osteoarthritis are typically prescribed acetaminophen, nonsteroidal anti-inflammatory drugs, and—if these agents do not provide sufficient relief—opioids.

How this classification was reachedexpand
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.
