Reported arm summaries

Values as reported by the source. Dispersion is the type the source recorded.
Study arm	Reported value	Dispersion	Participants
Mg sulphate group	17.45 score	SD 4.32	n=40
Control group	22.4 score	SD 3.29	n=40

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

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 Magnesium sulphate changed insomnia severity compared with general anesthesia in patients undergoing lumbar fixation.
Who was studied: patients undergoing lumbar fixation; reported arm sizes — Mg sulphate group n=40, Control group n=40
How it was designed: randomized controlled trial
Studied intervention: Magnesium sulphate — route/context: intravenous
Compared against: general anesthesia
What was measured, and when: insomnia severity (ISI), at 2 weeks after surgery.
What the authors reported: Reported arm summaries — Mg sulphate group: 17.45 score (SD 4.32; n=40); Control group: 22.4 score (SD 3.29; n=40). Reported p < 0.001.

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.
