Abstract
INTRODUCTION: Knee osteoarthritis, the most prevalent health condition in women, induces pain, functional disability, and substantial impact on the quality of life, imposing significant challenges in both public health and socioeconomic resources. Treatment for knee osteoarthritis encompasses various approaches, including non-pharmacological, pharmacological, and surgical interventions. Within the spectrum of non-pharmacological therapies, cupping therapy emerges as an alternative therapy that hypothetically aims to control symptoms associated with this population. However, recent systematic reviews highlight not only the lack of consensus on its effectiveness but also demonstrate a notable risk of methodological bias in studies involving patients with knee osteoarthritis. This gap in understanding and the presence of methodological limitations signal the need for more in-depth and robust investigations in individuals receiving this intervention with this health condition. OBJECTIVE: To assess the effects of dry cupping therapy on resting and moving pain in individuals with knee osteoarthritis. METHOD: A randomized, blind, allocation-concealed clinical trial with intention-to-treat analysis. Sixty-two clinically diagnosed women with knee osteoarthritis were randomized into two groups: experimental and control. The experimental group (n = 31) received the application of five (n=5) dry cups on the knee, and the control group (n = 31) underwent the same procedure but with a sham dry cupping therapy without vacuum. Both interventions were administered twice (2x) a week for a period of 6 weeks, with sessions lasting 15 minutes. The primary outcome was resting and moving pain (Numeric Pain Rating Scale), and secondary outcomes included knee health status (Western Ontario and McMaster Universities Osteoarthritis Index), quality of life (Short-form 36), functional capacity (30second Chair Stand Test, 40-meter Walk Test, 8-Step Stair Climb Test), and global perceived effect. Participants were assessed before the start of the intervention, after three and six weeks of treatment, and again one month after the interventions ended. A significance level of 5% and a 95% confidence interval were adopted for all statistical analyses. RESULTS: Both groups showed similar baseline characteristics. No statistically significant differences were identified between the groups regarding the primary outcome of resting pain intensity after 3 weeks (1.39, CI [-3.41; 0.64]), six weeks (-1.20, CI [(-3.17; 0.76)]), and ten weeks (-0.51, CI [(-3.01; 2.00)]). These results were corroborated in the secondary outcomes, where mean estimates and their confidence intervals excluded significant effects in all cases. These results suggest equivalence in responses between the experimental group and the control group over the evaluation period. CONCLUSION: Dry cupping therapy was similar to sham therapy in terms of reducing pain, disability, functional capacity, quality of life, or overall perceived effect in women with knee osteoarthritis.

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.
