Causal relationship between dietary patterns and the risk of developing chronic renal failure: a Mendelian randomization study.
Article in Genes & nutrition, 2025. 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
purposePrior observational studies and experimental research have suggested a link between dietary patterns and the risk of developing chronic renal failure (CRF). Nevertheless, the causality of that relationship is still uncertain. The aim of the present study was to investigate the causal relationship between the dietary intake of 18 different foods/beverages and the risk of developing CRF through the application of Mendelian randomization (MR) analysis.
methodsWe conducted a two-sample MR study. The exposure and outcome data were obtained from the UK Biobank and European Bioinformatics Institute (EBI) databases, respectively. All the data were obtained from the IEU Open GWAS Project. Five methods were used in this MR analysis. We also conducted a series of sensitivity analyses to ensure the validity of the results.
resultsDried fruit intake (OR (95% CI) = 0.447(0.271-0.737), p = 0.002) and cheese intake (OR (95% CI) = 0.678(0.515-0.893), p = 0.006) were associated with a reduced risk of developing CRF, whereas frequent alcohol intake (OR (95% CI) = 1.238(1.052-1.456), p = 0.010) was associated with an increased risk of developing CRF. The sensitivity analysis revealed that our results were robust.
conclusionsOur research provides genetic evidence that dried fruit and cheese intake are associated with a decreased risk of developing CRF, whereas frequent alcohol intake is associated with an increased risk of developing CRF. However, additional investigations are needed to verify our findings.
