Abstract
Previous studies have shown chondroitin sulfate and glucosamine hydrochloride have beneficial effects on symptoms of osteoarthritis of the knee. Our aim was to study the effect of a daily dose of 1500 mg of glucosamine hydrochloride (GH) and 1200 mg of chondroitin sulfate (CS) taken for twelve weeks on subjects diagnosed with capsulitis, disk displacement, disk dislocation, or painful osteoarthritis of the temporomandibular joint (TMJ). Forty-five subjects were enrolled in the study and were randomly assigned to either an active medication group or a placebo group. Eleven subjects were lost from the study for various reasons, resulting in fourteen subjects remaining in the active medication group and twenty subjects remaining in the placebo group. Subjects taking CS-GH had improvements in their pain as measured by one index of the McGill Pain Questionnaire, in TMJ tenderness, in TMJ sounds, and in the number of daily over-the-counter medications needed. Subjects taking the placebo medication had improvements in their pains as measured by the visual analog scale and by four indices of the McGill Pain Questionnaire. Additional studies are required to evaluate the clinical effectiveness of CS-GH and to determine the exact mechanism by which CS-GH affects the articular cartilage of synovial joints.

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 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 it
