Blood metabolites, mitochondrial biofunction, and cervical cancer: a bidirectional Mendelian randomization study.
Article in BMC women's health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionBlood metabolites and mitochondrial biological functions are associated with the occurrence and development of cancer, but the potential causal relationship between them and cervical cancer remains unknown. This bidirectional two-sample Mendelian randomization study aims to investigate the potential causal relationship between blood metabolites, mitochondrial biofunction and cervical cancer.
methodsIn this study, the blood metabolites and mitochondrial biofunction datasets were used as exposure factors, and the cervical cancer dataset from the Finnish dataset was used as the outcome. The study employed single nucleotide polymorphisms (SNPs) as instrumental variables and utilizes Inverse Variance Weighted (IVW), MR Egger, and Weighted Median methods for Mendelian randomization analysis. Sensitivity analysis was used to assess the reliability of the results. We also performed subgroup analysis based on the pathological types of cervical cancer. To further illuminate the possible metabolic mechanisms, MetaboAnalyst 6.0 tool was employed for metabolic pathway analysis.
resultsThe results indicated that 25 blood metabolites and 3 mitochondrial biofunctions have a potential causal relationship with cervical cancer. Among these blood metabolites, they can be categorized into fatty acid metabolites, bile acid metabolites, amino acid metabolites, hormone metabolites, caffeine metabolites, and others. Subgroup analysis reveals that different pathological types of cervical cancer have distinct potential risk and protective factors. Furthermore, metabolic pathway analysis suggests that linolenic acid metabolism exhibits strong anti-tumor potential. Specifically, Linolenate [alpha or gamma; (18:3n3 or 6)] showed an OR value of 0.81 (95% CI: 0.67-0.99), indicating a potential causal relationship between lipid metabolism and cervical cancer.
conclusionsBlood metabolites and mitochondrial biofunction have potential causal relationships with cervical cancer, which provides new insights for further research on the etiology and treatment of cervical cancer.
