Association between chronic kidney disease and colorectal cancer: evidence from meta-analysis and Mendelian randomization.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveObservational studies have yielded inconsistent findings on the relationship between chronic kidney disease (CKD) and the risk of colorectal cancer (CRC). This research utilized a meta-analysis of cohort studies along with two-sample Mendelian randomization (MR) approaches to explore the causal impact of CKD on CRC.
methodsA thorough search was performed across PubMed, Web of Science, Embase, and the Cochrane Library, encompassing all relevant studies from their inception until December 20, 2024. The data on the causal link between CKD and CRC were pooled using risk ratio (RR), with findings reported within 95% confidence interval (CI). For MR analysis, data were synthesized from genome-wide association studies (GWAS) that concentrated on CKD and CRC in cohorts of European descent. The inverse-variance weighted (IVW) approach was utilized as the primary method for MR analysis.
resultsThis meta-analysis encompassed 8 cohort studies involving 613,135 CKD patients and 733,068 controls. The pooled results revealed that CKD was associated with an increased risk of CRC in the total population (RR: 1.332, 95% CI 1.084-1.637, 95% prediction interval [PI] = 0.669-2.651). Subgroup analysis indicated that the association between CKD and elevated CRC risk was more pronounced in individuals younger than 50 years (RR: 2.119, 95% CI 1.205-3.725, 95% PI = 0.276-16.284) and in women (RR: 1.550, 95% CI 1.121-2.144, 95% PI = 0.594 to 4.043). Further MR analysis, using the IVW approach, showed a significant causal connection between CKD and the heightened CRC risk (odds ratio [OR]: 1.171, 95% CI 1.063-1.289, p = 0.001). Results from the sensitivity analyses provided no evidence of heterogeneity or horizontal pleiotropy in MR analysis.
conclusionEvidence from meta-analysis and MR analysis suggested that CKD may increase the risk of CRC. It remains essential to further investigate the relationship between CKD and CRC incidence across diverse ethnic populations.
