Magnesium and Zinc Are Associated with Sleep Quality in Saudi Adults: Evidence from a Cross-Sectional Study.
Article in Nutrients, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStudies that examine magnesium (Mg), zinc (Zn), and copper (Cu) in relation to sleep in the Middle East and North Africa are limited. We aim to assess the associations between serum and dietary Mg, Zn, and Cu levels and sleep quality in Saudi adults.
methodsA cross-sectional study was conducted among 1041 adults. Sleep quality was assessed using the Arabic Pittsburgh Sleep Quality Index (PSQI). Serum mineral levels were quantified biochemically, and dietary intake information was obtained. We utilized logistic regression to estimate the odds ratios for poor sleep (PSQI-P) in relation to serum and dietary indices in a crude model and after adjustment for confounders.
resultsSerum Mg deficiency (<1.8 mg/dL) increased the odds of PSQI-P by 30% in the crude and age-adjusted models, with attenuation after further adjustment, suggesting partial mediation by lifestyle and metabolic factors. Mg deficiency was associated with PSQI-P (1.8-fold higher odds) after full adjustment. Dietary Mg levels below the DRI were independently associated with poor sleep across models. Higher serum Zn tertiles were associated with 40% lower odds of PSQI-P, and Zn deficiency (<80 µg/dL) demonstrated a three-fold independent increase in risk. Neither serum nor dietary intake levels of Cu demonstrated an association with sleep quality.
conclusionIn Saudi adults, serum and dietary Mg levels were associated with poor sleep, particularly in males, while the serum Zn concentration exhibited a modest inverse association at higher levels. Further longitudinal studies are warranted.
