A randomized controlled trial to evaluate the slow‐acting symptom‐modifying effects of colchicine in osteoarthritis of the knee: A preliminary report
Bibliographic record
Abstract
OBJECTIVE: To determine if colchicine added to nimesulide may have a beneficial effect on osteoarthritis (OA) of the knee. METHODS: Colchicine 0.5 mg twice daily or placebo was added to nimesulide (a nonsteroidal antiinflammatory drug) in 36 patients with OA of the knee in a randomized, double-blind, placebo-controlled trial over a 5-month period. RESULTS: The 30% improvement rate at 20 weeks was higher in the colchicine group than in the control group receiving placebo, as measured by total Western Ontario and McMaster University Osteoarthritis scores (57.9% versus 23.5%) and visual analog scale for index knee pain (52.6% versus 17.6%) (primary measures of response). The significance persisted on combined analysis by Mantel-Haenszel test (P = 0.062). Comparison of means also showed significant improvement in the colchicine group versus the control group in a multivariate analysis performed using T(2) test (P = 0.0115). CONCLUSION: Among patients with OA of the knee, the group receiving colchicine plus nimesulide exhibited significantly greater symptomatic benefit at 20 weeks than did the control group receiving nimesulide plus placebo.

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.
