Single study

PMID 39498904: Computerized Mental Performance Assessment System (COMPASS)

  • AI-extracted — pending human review
  • Extraction status: machine extracted. Source status is not human clinical review.
  • Publication status: published. Record review status: not reviewed.
  • Not poolable: one source-reported result, not a pooled treatment estimate.

Authors reported a direction only for episodic memory, working memory, and accuracy of attention (Computerized Mental Performance Assessment System (COMPASS)): favours the studied intervention.

Reported p < 0.05.

  • Studied route/context: orally.

adults with self-reported cognitive and energy problems; prospective, randomized, placebo-controlled study. Ashwagandha (Withania somnifera) root extract (ARE) 600 mg/day versus identical placebo. episodic memory, working memory, and accuracy of attention (Computerized Mental Performance Assessment System (COMPASS)) at 8 week baseline.

That’s the gist — a fine place to stop. This describes the studied groups, not personal suitability.

Limitations and interpretation bounds

  • One generalized p<.05 statement covers the listed three COMPASS items; no item-specific significance, effect sizes, confidence intervals, or exact p-values are given.
  • Other outcomes with baseline changes and reported safety are retained in inventory; the abstract does not clearly state between-group inferential comparisons for those outcomes.
  • The abstract describes participants as healthy subjects aged 30–75 years and separately as adults with self-reported cognitive and energy problems; the population field anchors the latter, and both descriptions are retained.
  • Authors report greater improvement from baseline with ARE versus placebo across the three COMPASS items, with one generalized p<0.05 statement for the bundle; do not assign significance separately to each item.

  3. Guarded views

A finding keeps the same identity, version and evidence hash across its views. Source status is not human clinical review.

Eligibility is not a live presence check. Contextual links below have a current guarded scope match. A linked page’s filters, safety checks and availability can still prevent it from displaying this finding. A match does not establish an individual benefit.

Check actual public destinations

Eligibility and displayed coverage are different. This optional check reads the public responses below without signing in. It checks this exact finding version and hash, and rechecks current source authority before and after. Proven nonmatches are not coverage gaps; unavailable scope reads leave applicability unknown. Those destinations are not fetched. It cannot inspect private saves.

No actual-presence claim is made until you run the check.
