Investigating the role of inflammatory cytokines in mediating the effect of gut microbiota on gastrointestinal cancers: a mendelian randomization study.

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
purposeThe purpose of this study is to explore the causal relationship between gut microbiota and gastrointestinal (GI) cancers and to investigate the potential mediating factors influencing the development of GI cancers.
methodsUsing data from genome-wide association studies (GWAS), we employed two-sample Mendelian randomization (TSMR) to explore the relationship among gut microbiota, inflammatory cytokines and GI cancers. Subsequently, a multivariable Mendelian randomization (MVMR) analysis was meticulously conducted to perform a mediation analysis, thereby estimating the proportion of mediation effects conferred by inflammatory cytokines.
resultsTSMR analysis established a causal relationship between 23 gut microbiota taxa and 11 inflammatory cytokines with GI cancers. Specifically, 7 gut microbiota taxa were associated with an increased risk of gastric cancer (GC), 6 with small intestine cancer, and 10 with colorectal cancer (CRC). Among the inflammatory cytokines, 4 were linked to GC risk, 3 to small intestine cancer, and to CRC. Mediation analysis further indicatedthat tumor necrosis factor ligand superfamily member 12 (TNFSF12) mediated 9.703% (95% CI 0.108%~15.891%) of the total effect of genus Ruminiclostridium9 on GC.
conclusionOur findings support a causal relationship between gut microbiota, inflammatory cytokines, and GI cancers. These biomarkers provide new insights into the mechanisms underlying GI cancers and have the potential to improve strategies forprevention, diagnosis, and treatment.
