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
backgroundAbout 5%-10% of the world's population is affected by gastric ulcers, which can result in gastrointestinal perforation and bleeding. Consequently, we aimed to investigate whether blocking TNF-α type 1 receptor (TNFR1) with CAY10500 could diminish experimentally induced gastric ulcer (GU) in rats by modulating vascularization.
methodsRats were administered with a single oral dose of 80 mg/kg of indomethacin to produce gastric ulcers. Subsequently, some rats were given 1 mg/kg of CAY10500 orally. Gastric samples were used to assess the genetic expression and protein levels of TNFR1, VEGF, ERK, PI3K, AKT (also known as PKB), and ICAM-1. Gastric sections underwent electron microscopic examination and were subjected to hematoxylin and eosin staining and immunostaining using anti-TNFR1, anti-VEGF, and anti-ICAM-1 antibodies.
resultsCAY10500 demonstrated the ability to inhibit the expression of TNFR1. Examination of micro-images of GU using electron microscopy or H/E staining revealed extensive necrosis, resulting in the complete loss of regular ultrastructural features of epithelial nuclei and cytoplasmic organelles, as well as the loss of tight junctions and disruption of cell membranes. Significantly, the administration of CAY10500 mitigated these effects. Furthermore, CAY10500 significantly elevated the expressions of VEGF, ERK, PI3K, and AKT, which was associated with a significant reduction in the expression of ICAM-1.
conclusionCAY10500 effectively improved experimentally induced GU in rats. It works by inhibiting TNFR1 and activating angiogenesis and cell proliferation pathways, leading to gastric tissue healing. CAY10500 significantly reduced the adhesion molecule pathways.
