A randomized controlled trial to evaluate the effectiveness of an exercise program in women with rheumatoid arthritis taking low dose prednisone.
Bibliographic record
Abstract
OBJECTIVE: To evaluate the effects of a 12 month, weight bearing, aerobic exercise program on disease activity, physical function, and bone mineral density (BMD) in women with rheumatoid arthritis (RA) taking low dose prednisone. METHODS: A group of women with RA (n = 23) not receiving steroid therapy and in American College of Rheumatology functional class I or II was compared to 30 steroid treated patients with similar demographics. The latter group was randomized to usual care (n = 16) or an aerobic, weight bearing exercise program (n = 14) 3 times a week for 12 months. All subjects were recruited from an outpatient rheumatology clinic or physical therapy department and met the study inclusion criteria. Outcome measures included disease activity (erythrocyte sedimentation rate, active joint count), physical function (Health Assessment Questionnaire disability index, activity level) and BMD of the spine and femoral neck (by dual energy projection radiology). RESULTS: Subjects in the exercise group had a small but nonsignificant decrease in disease activity and statistically significant improvements in function (p = 0.05) and activity levels (p = 0.05). BMD remained unchanged in the exercise group, decreased significantly (p = 0.004) in the nonsteroid comparison group (hip), and changed nonsignificantly in the control group. However, between-group changes in spinal BMD of the steroid treated groups was not significant (p = 0.09). CONCLUSION: Women with RA taking low dose steroid therapy can safely participate in a dynamic, weight bearing exercise program with positive effects on their physical function, activity and fitness levels, and BMD with no exacerbation of disease activity.

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.
