Appraising the Role of Circulating Concentrations of Micronutrients in Hypertension: A Two-sample, Multivariable Mendelian Randomization 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
Background: Hypertension poses a significant global health challenge, warranting exploration of novel preventive measures. This study aimed to investigate the role of circulating concentrations of various micronutrients in hypertension using a Mendelian randomization (MR) approach. Methods: Data on hypertension were obtained from FinnGen, comprising 55,917 cases and 162,837 controls of European ancestry. Fifteen micronutrients were evaluated and selected based on genome-wide association studies (GWAS) data. Instrumental single nucleotide polymorphisms (SNPs) were chosen according to strict criteria. Univariable Mendelian randomization (UVMR) analysis was conducted using the inverse variance weighted (IVW) method, supplemented by sensitivity analyses. Multivariate Mendelian randomization (MVMR) analysis was performed to assess interactions between micronutrients. Results: In UVMR analysis, the IVW method revealed a potential influence of copper (OR = 1.052, 95% CI: 1.006-1.099, Conclusion: Circulating zinc levels may be a potential risk factor for hypertension, while the association with other micronutrients remains inconclusive. These findings suggest that reducing zinc intake within a healthy range may help lower hypertension risk. Future research should further explore the role of zinc and nonlinear associations for a more comprehensive understanding.
