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 sleep quality (PSQI): favours the studied intervention.

Reported p < 0.05.

Studied combination: 1.9 mg melatonin + 200 mg elemental magnesium.
Studied route/context: unclear.

otherwise healthy individuals with sleep disturbances; double-blinded, randomized, crossover trial. supplement condition versus placebo. sleep quality (PSQI) at 4 week intervention.

Source-reported direction

Source-reported direction: favours the studied intervention.

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.
Participants / population	otherwise healthy individuals with sleep disturbances
Study design	double-blinded, randomized, crossover trial
Studied intervention	supplement condition
Studied combination	1.9 mg melatonin + 200 mg elemental magnesium
Studied route / context	unclear
Comparator	placebo
Measured outcome	sleep quality (PSQI)
Timepoint	4 week intervention

Limitations reported for this finding

AI-extracted; pending human review.
A combined melatonin-magnesium intervention; no isolated ingredient effect is established.
Crossover results lack a supported magnitude or paired uncertainty in the accepted source.
Average PSQI scores still indicated poor sleep quality in both conditions.

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.

What the paper set out to compare: Whether supplement condition changed sleep quality compared with placebo in otherwise healthy individuals with sleep disturbances.
Who was studied: otherwise healthy individuals with sleep disturbances
How it was designed: double-blinded, randomized, crossover trial
Studied intervention: supplement condition — studied as a combination: 1.9 mg melatonin + 200 mg elemental magnesium — route/context: unclear
Compared against: placebo
What was measured, and when: sleep quality (PSQI), at 4 week intervention.
What the authors reported: Source-reported direction: favours the studied intervention. Reported p < 0.05.

Limitations and interpretation bounds

AI-extracted; pending human review.
A combined melatonin-magnesium intervention; no isolated ingredient effect is established.
Crossover results lack a supported magnitude or paired uncertainty in the accepted source.
Average PSQI scores still indicated poor sleep quality in both conditions.

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.
