- 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
| Participants / population | Eighty 35-55-year-olds with self-assessed sleep problems |
|---|---|
| Study design | randomized, double-blind, placebo-controlled, parallel-arm study |

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.
