Causal relationship between dietary habits and low hand grip strength: A Mendelian randomization study.
Article in Medicine, 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
A large number of studies have shown a close association between dietary habits and low hand grip strength. However, the presence of a causal connection between dietary habits and low hand grip strength remains unclear. All genome-wide association studies of dietary habits summary statistics were run in BOLT-LMM software (Broad Institute) using linear mixed models with 10 genetic principal components and genotyping array as covariates, and all phenotypes were averaged over multiple Food Frequency Questionnaires, adjusted for age and sex, and inverse normal transformed. The extracted single nucleotide polymorphisms explored the relationship between dietary habits and low hand grip strength by inverse variance weighted (IVW), Mendelian randomization-Egger (MR-Egger), and MR-pleiotropy residual sum and outlier. IVW estimates indicated that different dietary habits had a causal association with low hand grip strength, including drinking currently with various meals (beta: -0.432, 95% confidence interval [CI]: -0.669 to -0.194, PIVW = 3.70E-04), semi-skimmed milk (beta: -0.825, 95% CI: -1.626 to -0.024, PIVW = 4.30E-02), flora and benecol spread (beta: 0.210, 95% CI: 0.037-0.382, PIVW = 1.80E-02), tablespoons of raw vegetables per day (beta: -0.361, 95% CI: -0.563 to -0.158, PIVW = 4.80E-04), no dairy restrictions (beta: 1.223, 95% CI: 0.372-2.074, PIVW = 4.90E-03) and no eggs, dairy, wheat, or sugar restrictions (beta: 1.027, 95% CI: 0.377-1.677, PIVW = 2.00E-03). All significant MR results are false discovery rate-corrected. This MR investigation revealed that various dietary habits were causally linked to low hand grip strength. Further investigations into their relationships are necessary and will contribute to preventing low hand grip strength.
