Effectiveness of a Cucumber Extract Supplement on Articular Pain in Patients with Knee Osteoarthritis: A Randomized Double-Blind Controlled Clinical Trial
Bibliographic record
Abstract
This 8-week randomized double-blind placebo-controlled study aimed to assess the effectiveness of supplementation with an extract of Cucumis sativus L. (20 mg/day) on pain and other variables in patients with knee osteoarthritis (OA) over 40 years. The change in pain intensity using a 1–10 cm visual analog scale (VAS) was the primary endpoint. Fifty-five patients (mean age 50.6 ± 8.6 years) were included (experimental group, n = 29; placebo, n = 26). VAS scores for pain decreased significantly in both study groups, but decreases were higher in the experimental group (between-group p = 0.013). Improvements in pain, stiffness, and physical function according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were also significantly higher in the experimental group. The Timed Up and Go test result also decreased significantly in the experimental group. An improvement in muscle function was associated with significant increases in isokinetic and isometric dynamometry variables, particularly for isometric 60°·s−1 and 180°·s−1 knee flexion exercises in the experimental group. Plasma levels of interleukin-1-beta (IL-1β) and matrix metalloproteinase-3 (MMP-3) also decreased significantly in the experimental group. Based on the beneficial effects of cucumber on symptomatology and inflammatory and cartilage degradation biomarkers in knee OA, cucumber extract supplementation may a useful natural approach to maintain healthy 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.
