Source-reported research findings

AI-extracted — pending human review. These findings retain the studied context and are not pooled treatment estimates.

PMID 39252819: Oura ring

  • 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.

Direction for deep sleep score, REM sleep score, light sleep time, and activity and readiness parameters activity score, activity daily movement score, readiness score, readiness activity balance, and readiness sleep balance (Oura ring) remains unresolved in this record.

Reported p < 0.05.

  • Studied combination: MgT.

Eighty 35-55-year-olds with self-assessed sleep problems; randomized, double-blind, placebo-controlled, parallel-arm study. 1 g/day of MgT versus placebo. deep sleep score, REM sleep score, light sleep time, and activity and readiness parameters activity score, activity daily movement score, readiness score, readiness activity balance, and readiness sleep balance (Oura ring) at 21 days MgT or placebo.

Source-reported direction

Source-reported direction: unclear.

No between-arm contrast, interval estimate or pooled result is calculated here; the values above are exactly as the source reported them.

Studied context

The context this result was produced in. It bounds what the result can be applied to.

Limitations reported for this finding

  • The abstract reports bundled outcomes without endpoint-specific effect sizes, confidence intervals, or arm-level means/SDs.
  • The abstract reports 80 participants but does not state allocation counts by arm.
  • The abstract lists standardized questionnaires including the Insomnia Severity Index, Leeds Sleep Evaluation Questionnaire, and Restorative Sleep Questionnaire; it does not map each listed symptom result to a specific questionnaire.
  • The result sentence explicitly says MgT significantly improved vs placebo, but the current direction-source guard does not accept this “improved vs” phrase form; direction remains unclear pending source-matched guard support. No inferential direction is invented.
  • “Safe and well tolerated” appears in the abstract without adverse-event counts; this is not a safety guarantee.

What this paper studied

  • Verified extracted record
  • AI-extracted — pending human review
  • Source status is not human clinical review. Interpretation bound: a single source-reported result, not a pooled treatment estimate.

Each statement below is composed only of fields extracted from this paper's own source document and bound to a locator in it. It restates the study — it is not an interpretation, a grade or a recommendation, and it is not a quotation of the authors' wording. This record carries 2 extracted findings; the explanation leads with the first and every finding is shown in full below.

Limitations and interpretation bounds

  • The abstract reports bundled outcomes without endpoint-specific effect sizes, confidence intervals, or arm-level means/SDs.
  • The abstract reports 80 participants but does not state allocation counts by arm.
  • The abstract lists standardized questionnaires including the Insomnia Severity Index, Leeds Sleep Evaluation Questionnaire, and Restorative Sleep Questionnaire; it does not map each listed symptom result to a specific questionnaire.
  • The result sentence explicitly says MgT significantly improved vs placebo, but the current direction-source guard does not accept this “improved vs” phrase form; direction remains unclear pending source-matched guard support. No inferential direction is invented.
  • “Safe and well tolerated” appears in the abstract without adverse-event counts; this is not a safety guarantee.

One finding, several views

Where these findings appear

  1. Versioned source
  2. Admitted finding
  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.

Review the current evidence and explicitly choose whether to save it. This public page does not know whether anyone has saved it. Nothing is saved by opening the link.

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.
