Response of symptoms and synovitis to intra-muscular methylprednisolone in osteoarthritis of the hand: an ultrasonographic study
Bibliographic record
Abstract
OBJECTIVE: To examine the relationship between ultrasound (US)-detected synovial pathology in hand OA and the clinical response to parenteral corticosteroids. METHODS: People with symptomatic OA of the hand completed questionnaires [visual analogue scale (VAS) pain, Australian Canadian Osteoarthritis Hand Index and VAS global] and underwent an US examination of both hands prior to receiving an i.m. dose of methylprednisolone. Four- and twelve-week assessments were performed to assess therapeutic response. RESULTS: Thirty-six subjects with established OA were enrolled. Twenty-four (67%) subjects met the primary end-point of a 20% reduction in VAS pain, 25 (69.4%) met the Osteoarthritis Research Society International response criteria at 4 weeks. Overall in the group, there was a reduction in levels of pain in the most painful joint, pain in all joints and in global disease activity at 4 weeks (P < 0.001, P < 0.001 and P < 0.001, respectively). Reduction in symptoms was not associated with a statistically significant reduction in US-detected synovial hypertrophy or power Doppler signal. CONCLUSIONS: In this observational study, parenteral corticosteroids were associated with a statistically significant reduction in symptoms, but no statistically significant reduction in US-detected synovial inflammation. The latter finding may, however, reflect the relatively low levels of synovial inflammation detected ultrasonagraphically in hand joints.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
