Differences in Safety of Nonsteroidal Antiinflammatory Drugs in Patients With Osteoarthritis and Patients With Rheumatoid Arthritis
Bibliographic record
Abstract
OBJECTIVE: To determine the relative risks of cardiovascular (CV), gastrointestinal (GI), and renal adverse events during long-term treatment with celecoxib, compared with ibuprofen and naproxen, in patients with osteoarthritis (OA) and patients with rheumatoid arthritis (RA). METHODS: A total of 24,081 patients with OA or RA who had a moderate or high risk for CV disease were enrolled internationally into a double-blind randomized controlled trial. Interventions included celecoxib at a dosage of 100-200 mg twice daily, ibuprofen at a dosage of 600-800 mg 3 times daily, or naproxen at a dosage of 375-500 mg twice daily. The main outcomes were the first occurrence of a major adverse CV event, GI event, or renal event, and mortality. RESULTS: In the subgroup of patients with OA, the risk of a major adverse CV event was significantly reduced when celecoxib was compared with ibuprofen (hazard ratio [HR] 0.84, 95% confidence interval [95% CI] 0.72-0.99), but no significant difference was observed when celecoxib was compared with naproxen. In the RA subgroup, comparisons of celecoxib versus ibuprofen and celecoxib versus naproxen for the risk of major adverse CV events revealed HRs of 1.06 (95% CI 0.69-1.63) and 1.22 (95% CI 0.78-1.92), respectively. In the OA subgroup, comparisons of celecoxib versus ibuprofen for the risk of GI events showed an HR of 0.68 (95% CI 0.51-0.91), and a comparison of celecoxib versus naproxen showed an HR of 0.73 (95% CI 0.55-0.98). Duplicate comparisons in patients with RA revealed HRs of 0.48 (95% CI 0.22-1.07) and 0.54 (95% CI 0.24-1.24), respectively. In patients with OA, a comparison of celecoxib versus ibuprofen for the risk of renal events showed an HR of 0.58 (95% CI 0.40-0.82). In patients with RA, celecoxib treatment was associated with significantly lower mortality compared with naproxen treatment (HR 0.47, 95% CI 0.25-0.88). CONCLUSION: Treatment with celecoxib at approved dosages conferred a similar or lower risk of CV, GI, and renal adverse events compared with treatment with ibuprofen or naproxen in patients with OA and 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.
