Abstract
Abstract The special formulation MA212 (Rosaxan) is composed of rosehip (Rosa canina L.) puree/juice concentrate, nettle (Urtica dioica L.) leaf extract, and devilʼs claw (Harpagophytum procumbens DC. ex Meisn. or Harpagophytum zeyheri Decne.) root extract and also supplies vitamin D. It is a food for special medical purposes ([EU] No 609/2013) for the dietary management of pain in patients with gonarthritis. This 12-week randomized, placebo-controlled double-blind parallel-design study aimed to investigate the efficacy and safety of MA212 versus placebo in patients with gonarthritis. A 3D-HPLC-fingerprint (3-dimensional high pressure liquid chromatography fingerprint) of MA212 demonstrated the presence of its herbal ingredients. Ninety-two randomized patients consumed 40 mL of MA212 (n = 46) or placebo (n = 44) daily. The Western Ontario and McMaster Universities Arthritis Index (WOMAC), quality-of-life scores at 0, 6, and 12 weeks, and analgesic consumption were documented. Statistically, the initial WOMAC subscores/scores did not differ between groups. During the study, their means significantly improved in both groups. The mean pre-post change of the WOMAC pain score (primary endpoint) was 29.87 in the MA212 group and 10.23 in the placebo group. The group difference demonstrated a significant superiority in favor of MA212 (pU < 0.001; pt < 0.001). Group comparisons of all WOMAC subscores/scores at 6 and 12 weeks reached same significances. Compared to placebo, both physical and mental quality of life significantly improved with MA212. There was a trend towards reduced analgesics consumption with MA212, compared to placebo. In the final efficacy evaluation, physicians (pChi < 0.001) and patients (pChi < 0.001) rated MA212 superior to placebo. MA212 was well tolerated. This study demonstrates excellent efficacy for MA212 in gonarthritis patients.

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
