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
The etiology of liver cancer remains poorly understood, particularly regarding its potential association with dietary patterns rich in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP). This study investigated the genetic relationships between FODMAP-related dietary intake and liver cancer risk and further assessed whether proteins involved in efferocytosis and trogocytosis mediate these associations. This study applied two-sample Mendelian randomization (MR) and mediation MR analyses to examine the links among FODMAP-related dietary factors, trogocytosis, efferocytosis, and liver cancer. Summary statistics were obtained from MVP-GWAS for liver cancer, deCODE for trogocytosis and efferocytosis, and the UK Biobank for FODMAP dietary traits. A two-step mediation MR analysis was then performed to determine whether the pathways of efferocytosis and trogocytosis mediated the genetic associations between FODMAP foods and liver cancer, with mediation proportions calculated accordingly. MR analyses revealed that higher consumption of cheese (OR = 0.548, 95% CI = 0.404-0.743), fresh fruit (OR = 0.375, 95% CI = 0.194-0.727), cereal (OR = 0.575, 95% CI = 0.386-0.857), and dried fruit (OR = 0.539, 95% CI = 0.340-0.853) was significantly associated with a reduced risk of liver cancer. Protein-level analyses identified four trogocytosis- and efferocytosis-related proteins, TGFB3, EPOR, ELANE, and C3, that may mediate these dietary effects on liver cancer susceptibility. Mediation MR indicated that cheese intake influenced liver cancer risk indirectly by modulating TGFB3, EPOR, ELANE, and C3 expression, accounting for 8.8%, 25%, 1.8%, and 12.7% of the total effect, respectively. Sensitivity analyses for heterogeneity and pleiotropy supported the robustness of these findings. This study uncovers a potential molecular mechanism by which FODMAP-related dietary patterns may modulate liver cancer risk through the TGFB3/EPOR/ELANE/C3 signaling axis. These results provide genetic evidence and mechanistic insights supporting the role of FODMAP-oriented dietary strategies in liver cancer prevention, offering a theoretical basis for future public health interventions.
