Associations between cutaneous melanoma and prostate cancer: A bidirectional 2-sample Mendelian randomization study.
Article in Medicine, 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
Cutaneous melanoma (CM) and prostate cancer (PC) are both more prevalent in males. With the advancements in genetics and molecular biology, there has been a growing focus on exploring the potential genetic linkage between these 2 malignancies. Observational studies have indicated that the occurrence of CM is associated with the incidence of PC. However, the specific factors contributing to the heightened risk of CM remain unknown. The primary objective of this study was to investigate whether there exists a common (shared) genetic basis for both cancers using Mendelian randomization (MR). MR was employed to extract genetic data for CM and PC from genome-wide association studies. And applied inverse variance weighted (IVW), weighted median, simple median, MR-PRESSO and MR-RAPS to evaluate the association between CM and PC at genetic level. Sensitivity was assessed using Leave-one-out, MR-Egger, and MR-PRESSO, while heterogeneity was tested with the Cochran Q-test. IVW and other MR methods found no evidence for the effect of CM on the risk of PC, IVW analysis (OR = 0.96, 95% CI: 0.84-1.09, P = .521) and MR-Egger regression (OR = 1.35, 95% CI: 0.14-13.50, P = .810), and no evidence of the effect of PC on the risk of CM, IVW analysis (OR = 1.00, 95% CI: 0.90-1.12, P = .957) and MR-Egger regression (OR = 1.17, 95% CI: 0.66-2.06, P = .604). The results of the secondary analysis using GRS were in line with those obtained from the primary analysis, thus confirming the robustness and reliability of this study. Our findings do not provide any evidence supporting that genetic association between CM and PC.
