Low serum zinc levels and risk of incident atrial fibrillation/flutter: a multi-institutional study.
Article in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Atrial fibrillation/flutter (AF) is increasingly prevalent, and identification of modifiable risk factors is a priority. Zinc deficiency (ZD) has been implicated in cardiovascular disease, but large-scale evidence linking ZD to incident AF remains limited. Methods: We conducted a multi-institutional retrospective cohort study using the TriNetX Research Network, analyzing patients aged ≥40 years with documented serum zinc levels (index date) between 2010 and 2023. Patients were categorized as zinc-deficient (< 70 μg/dL, Results: ZD was associated with significantly increased AF risk during both the early (hazard ratios (HRs) 1.62, 95% confidence intervals (CIs) 1.39-1.90, Conclusion: ZD may serve as an important independent risk factor for incident AF, highlighting the potential value of incorporating zinc status into cardiovascular risk assessment and considering zinc supplementation as a cost-effective preventive strategy.
