Abstract
Background: Current pharmacologic therapies for patients with osteoarthritis are suboptimal. Objective: To determine the efficacy of Curcuma longa extract (CL) for reducing knee symptoms and effusion–synovitis in patients with symptomatic knee osteoarthritis and knee effusion–synovitis. Design: Randomized, double-blind, placebo-controlled trial. (Australian New Zealand Clinical Trials Registry: ACTRN12618000080224) Setting: Single-center study with patients from southern Tasmania, Australia. Participants: 70 participants with symptomatic knee osteoarthritis and ultrasonography-defined effusion–synovitis. Intervention: 2 capsules of CL (n = 36) or matched placebo (n = 34) per day for 12 weeks. Measurements: The 2 primary outcomes were changes in knee pain on a visual analogue scale (VAS) and effusion–synovitis volume on magnetic resonance imaging (MRI). The key secondary outcomes were change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and cartilage composition values. Outcomes were assessed over 12 weeks. Results: CL improved VAS pain compared with placebo by −9.1 mm (95% CI, −17.8 to −0.4 mm [P = 0.039]) but did not change effusion–synovitis volume (3.2 mL [CI, −0.3 to 6.8 mL]). CL also improved WOMAC knee pain (−47.2 mm [CI, −81.2 to −13.2 mm]; P = 0.006) but not lateral femoral cartilage T2 relaxation time (−0.4 ms [CI, −1.1 to 0.3 ms]). The incidence of adverse events was similar in the CL (n = 14 [39%]) and placebo (n = 18 [53%]) groups (P = 0.16); 2 events in the CL group and 5 in the placebo group may have been treatment related. Limitation: Modest sample size and short duration. Conclusion: CL was more effective than placebo for knee pain but did not affect knee effusion–synovitis or cartilage composition. Multicenter trials with larger sample sizes are needed to assess the clinical significance of these findings. Primary Funding Source: University of Tasmania and Natural Remedies Private Limited.

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
