Causal roles of dietary structure and types on prostate cancer risk: A mendelian randomization study.
Article in BMC cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundNumerous observational studies have reported a strong link between dietary habits and the risk of prostate cancer. However, these studies are susceptible to confounding factors. To address this question, we conducted a two-sample Mendelian randomization (MR) study to explore the causal relationship between dietary habits and prostate cancer.
methodsGenetic data for 25 different diet types were obtained from UK Biobank. Summary-level data on dietary composition and prostate cancer were obtained from a large genome-wide association study (GWAS). We employed the inverse variance weighted (IVW) for the primary analysis to examine the causal relationship between dietary components, dietary types, and prostate cancer. We also conducted sensitivity analyses using the Steiger filter, MR-Egger intercept test, Cochran's Q statistic, funnel plot, and leave-one-out analysis were used for sensitivity analysis to ensure the robustness of our findings.
resultIVW results showed that relative fat intake (OR = 0.57, 95%CI: 0.33-1.00, P < 0.05) and canned tomato intake (OR = 0.73, 95%CI: 0.60 ~ 0.87, P < 0.01) and green bean intake (OR = 0.85, 95%CI: 0.74 ~ 0.98, P = 0.03) may be protective factors for prostate cancer. In contrast, relative sugar intake (OR = 1.43, 95% CI: 1.03-2.00, P = 0.03) may increase the risk of prostate cancer.
conclusionsRelative fat intake, green bean intake, and canned tomato intake may have a protective causal effect against prostate cancer, while relative sugar intake may increase the risk of prostate cancer. R These insights have implications for developing prevention strategies and interventions targeting dietary intake to prevent prostate cancer.
