Abstract

fetched live from OpenAlex

BACKGROUND: COLD-fX (CVT-E002), a proprietary extract of the roots of North American ginseng (Panax quinquefolium), rich in poly-furanosyl-pyranosyl-saccharides, has been found efficacious in the prevention of respiratory infections in institutionalized seniors and healthy adults. OBJECTIVE: We examined the efficacy of COLD-fX in the prevention of acute respiratory illness (ARI) in community dwelling seniors. DESIGN: This was a randomized, double-blind, placebo controlled trial. INTERVENTION: The participants were asked to take 2 capsules/day of either COLD-fX or placebo (200 mg/ capsule) for a period of 4 months. SUBJECTS: A total of 43 community-dwelling adults aged 65 years or older were recruited. Following one month of intervention, subjects were immunized with influenza vaccine. OUTCOME MEASURES: Subjects recorded the incidence and duration of respiratory symptoms during the study. They also recorded the incidence of adverse events during the study. RESULTS: The frequency and duration of ARI during the first two months of the study was found to be similar in the two groups. However, during the last 2 months (November and December) significantly fewer subjects in the COLD-fX group 32% reported ARI compared to the placebo group 62%. The duration of symptoms during the last 2 months was significantly shorter in the COLD-fX group than the placebo group (5.6 days in the COLD-fX group vs 12.6 days in the placebo group). There was no influenza illness circulating in the community during the period of the study. CONCLUSIONS: Ingestion of COLD-fX by immunocompetent seniors during an early "cold and flu" season reduced the relative risk and duration of respiratory symptoms by 48% and 55%, respectively. Daily COLD-fX administration can thus be a safe, natural therapeutic means for the prevention of ARI in healthy seniors.

Not 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.
