Association of magnesium depletion score with all-cause and cardiovascular mortality in hyperlipidemia adults: a large nationwide population-based study.

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
backgroundMagnesium, an essential dietary trace element, plays a crucial role in numerous physiological processes, and its deficiency has been associated with the development of hyperlipidemia. However, its potential to predict long-term outcomes and inform risk stratification in hyperlipidemic patients remains underexplored.
methodsThis retrospective cohort study introduces the magnesium depletion score (MgDS), a novel index for quantifying magnesium deficiency, and investigates its association with mortality outcomes in individuals with hyperlipidemia. Data from 12,592 participants in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 were analyzed. Advanced statistical methods, including weighted Cox proportional hazards models, restricted cubic spline (RCS) analysis, Kaplan-Meier survival curves, and receiver operating characteristic (ROC) analysis, were employed to assess the association between MgDS and mortality risks.
resultsThe results indicate that higher MgDS is significantly associated with increased risks of both all-cause and cardiovascular mortality in individuals with hyperlipidemia, even after adjusting for confounders. Subgroup analyses identified prediabetes, smoking, and alcohol consumption as significant modifiers of this association. RCS analysis confirmed a linear relationship between MgDS and mortality, further supporting its value as a reliable predictor of long-term outcomes. ROC analysis demonstrated the potential of MgDS as an independent tool for predicting mortality at 1, 3, and 5 years. Notably, high MgDS levels in hyperlipidemic individuals with binge drinking habits were associated with significantly higher mortality risks.
conclusionsThese results establish MgDS as a promising biomarker for mortality risk stratification in patients with hyperlipidemia. This novel index offers important insights for clinical practice and could facilitate the development of tailored management strategies, particularly for high-risk hyperlipidemia populations, to mitigate long-term health risks.
