Ultrasound-guided corticosteroid injections for adhesive capsulitis more effective than placebo
Bibliographic record
Abstract
Commentary on: Prestgaard T, Wormgoor ME, Haugen S, et al. Ultrasound-guided intra-articular and rotator interval corticosteroid injections in adhesive capsulitis of the shoulder: a double-blind, sham-controlled randomized study. Pain 2015;156:1683–91.[OpenUrl][1][CrossRef][2][PubMed][3] Adhesive capsulitis (frozen shoulder or painful stiff shoulder) is relatively common. It is idiopathic: known associated factors include trauma, diabetes, prolonged immobilisation, age, stroke and autoimmune disease. While self-limited, pain and decreased range of motion can last up to 2–3 years. Therefore, there is practical value in therapeutic interventions to hasten symptom resolution. Arthroscopic examination suggests involvement of both the capsule and the rotator interval, defined as the space between the subscapularis and supraspinatus tendons, including the long head of the biceps tendon, the coracohumeral and the superior glenohumeral ligaments, and part of the joint capsule.1 Although corticosteroid injections appear to be more effective … [1]: {openurl}?query=rft.jtitle%253DPain%26rft.volume%253D156%26rft.spage%253D1683%26rft_id%253Dinfo%253Adoi%252F10.1097%252Fj.pain.0000000000000209%26rft_id%253Dinfo%253Apmid%252F25919473%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/external-ref?access_num=10.1097/j.pain.0000000000000209&link_type=DOI [3]: /lookup/external-ref?access_num=25919473&link_type=MED&atom=%2Febmed%2F21%2F2%2F71.atom

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
