Association Analysis Between Dietary Magnesium Intake and All-Cause and Cause-Specific Mortality in Individuals With Chronic Neck Pain.
Article in Molecular nutrition & food research, 2026. 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
This study investigated the association between dietary magnesium intake and all‑cause and cause‑specific mortality among individuals with chronic neck pain (CNP). We enrolled 2955 CNP patients aged ≥20 years from the 1999-2020 NHANES database and used Cox regression, subgroup analysis, and Mendelian randomization‑based mediation analysis to explore relevant associations and mechanisms. During follow‑up, 719 all‑cause deaths, 180 cardiovascular disease (CVD) deaths, and 179 cancer deaths occurred. Multivariable‑adjusted analyses showed that higher dietary magnesium intake was significantly associated with reduced CVD mortality, with each 1 g/day increment linked to a 78% lower risk. A non‑linear association with a threshold of 0.5181 g/day was found for cancer mortality, above which mortality risk dropped significantly. Subgroup analyses confirmed result robustness. Mediation analysis revealed that magnesium lowered all‑cause and CVD mortality directly and indirectly by reducing C‑reactive protein (CRP) levels. These findings indicate that higher dietary magnesium intake predicts lower mortality risk in CNP patients, partly via CRP‑mediated anti‑inflammatory pathways, supporting dietary magnesium optimization from whole‑food sources to improve long‑term prognosis.
