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
Introduction: Hepatic sinusoidal obstruction syndrome (HSOS) is a vascular liver disease with a high mortality rate, and treatment methods are limited. Rivaroxaban is an oral anticoagulant. This study aimed to investigate the pharmacological effect and potential mechanism of rivaroxaban on HSOS. Methods: In this study, we induced an HSOS mouse model in male C57BL/6J mice by administering monocrotaline orally. The mice were randomly divided into four groups: the control group, the rivaroxaban (RIV) group, the monocrotaline (MCT) group, and the monocrotaline + rivaroxaban (MCT + RIV) group. Liver function and histopathology were evaluated. 16S rDNA sequencing of the small intestinal contents, transcriptomic sequencing of small intestine tissues, real-time qPCR, Western blot analysis of liver tissues, and correlation analysis were conducted. Antibiotic (ABX) treatment and fecal microbiota transplantation (FMT) experiments were also performed to explore the role of the gut microbiota. Results: Compared with the MCT group, rivaroxaban alleviated serum biochemical liver function analysis and liver histopathology in the MCT + RIV group. Additionally, 16S rDNA sequencing of the small intestinal contents revealed that, compared with the MCT group, the MCT + RIV group presented increased relative abundances of Allobaculum and Pediococcus but decreased relative abundances of Streptococcus, Staphylococcus, and Candidatus Arthromitus. Mechanistically, integrated analyses, including transcriptomic sequencing of small intestin e tissues, real-time qPCR, Western blot analysis of liver tissues, and correlation analysis, demonstrated that rivaroxaban protected against MCT-HSOS by inhibiting the PI3K/Akt signaling pathway. In addition, antimicrobial cocktail (ABX) treatment eliminated the beneficial effects of rivaroxaban on liver function and histopathological injury, whereas fecal microbiota transplantation (FMT) from rivaroxaban-treated donors significantly ameliorated liver dysfunction and histological damage in MCT-HSOS mice. Discussion: These findings suggest that rivaroxaban alleviates hepatic sinusoidal obstruction syndrome in mice by modulating the gut microbiota and inhibiting the PI3K/Akt signaling pathway. Rivaroxaban may be a promising therapeutic option for treating HSOS.
