The association between diet and bladder cancer risk: a two-sample mendelian randomization.
Article in European journal of nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeBladder cancer (BC) is the ninth most common cancer globally, with notable gender and regional differences. Due to the inconclusive impact of diet on BC risk and the inherent biases from observational studies, this research investigates the causal role of dietary patterns (DPs) in BC risk using Two-Sample Mendelian Randomization (TSMR).
methodsGenetic variants were used as instrumental variables (IVs) to analyze 14 food/beverage items and four DPs. Summary-level exposure and outcome data were derived from UK Biobank GWAS (>500,000 participants). The inverse-variance weighted (IVW) method was the primary approach, supported by sensitivity tests including weighted median, MR-Egger regression, and MR-PRESSO.
resultsNo causal links were identified between BC risk and 14 specific foods or two DPs (Low-Caloric and Acquired Diet Patterns). However, greater adherence to PC1 (high in whole grains, fruits, and vegetables) was associated with a reduced BC risk (OR: 0.74, 95% CI 0.61-0.89, p < 0.05). In contrast, the Highly Palatable Dietary Pattern (HPDP), rich in processed and high-calorie foods, was linked to a more than twofold increase in BC risk (OR: 2.81, 95% CI 1.43-5.52, p < 0.05). These findings were consistent across sensitivity analyses, with no evidence of pleiotropy or heterogeneity.
conclusionsAdherence to PC1 may lower BC risk, while HPDP may increase it, emphasizing the relevance of overall dietary habits in BC prevention. Further research in diverse populations is recommended to develop more targeted prevention strategies and better translate findings into practice for improved BC-related public health outcomes.
