Developing a Preliminary Definition and Domains of Flare in Knee and Hip Osteoarthritis (OA): Consensus Building of the Flare-in-OA OMERACT Group
Bibliographic record
Abstract
Flare in knee and hip osteoarthritis (OA) is more than just an exacerbation of pain. Unstructured, semistructured, and focus group interviews followed by Delphi surveys with patients and health professionals (HP) generated candidate domains of an OA flare. Content analysis of interviews with 29 patients and 16 HP extracted 180 statements, which were grouped into 9 clusters. Delphi consensus with 50 patients (Australia, Canada, and France) and 116 HP (17 countries on 4 continents) identified 5 flare domains: pain, swelling, stiffness, psychological aspects, and effect of symptoms. Elements for a preliminary definition of an OA flare are proposed. Registered at clinicaltrials.gov NCT02892058.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
