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
Recent studies have indicated a correlation between gut microbiota (GM) and venous thromboembolism (VTE). However, the specific effects of GM on VTE-related immune factors remain largely unknown. Thus, we conducted a Mendelian randomization (MR) analysis to explore the relationships between GM, immune cells, and VTE. This mediation MR study utilized the summary-level data of respective genome-wide association study for 207 taxa and 205 bacterial pathways, 731 immune cell traits, and VTE. This MR design was deployed, and comprehensive sensitive analyses were followed to validate the robustness of the results. We used the inverse-variance weighted, Bayesian-weighted MR, MR-Egger regression, MR-Egger intercept test, Cochrane Q test, and leave-one-out analysis as the primary methods. We identified a suggestive association between 16 bacterial traits and VTE risk, with 3 taxa affecting VTE through 2 types of immune cells as mediators. For example, "c_Bacteroidia" was implicated in reducing the risk of VTE via "DN (CD4- CD8-) NKT % lymphocyte" cells. This study suggested the role of the specific GMs on the VTE risk, emphasizing the potential mediatory function of GM-related immune cells.
