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
Endothelial cell dysfunction plays an important role in the occurrence and development of sepsis, which is a consequence of the interaction between coagulation and inflammation. Kynurenine (KYN) is an endothelium-derived relaxing factor that makes a large contribution to sepsis pathophysiology. In this study, we investigated the influence of bone marrow mesenchymal stem cells (BMSCs) on KYN production by cultured endothelial cells. KYN and tryptophan (TRP) concentrations in cell supernatants were simultaneously measured with a high-performance liquid chromatography (HPLC) system equipped with a fluorescence detector (FLD) and an ultraviolet detector (UVD). Our results revealed that lipopolysaccharide-stimulated endothelial cells produced more KYN, which was accompanied by a parallel decrease in TRP. When co-cultured with BMSCs, KYN and TRP production were significantly decreased compared to lipopolysaccharide (LPS)-induction alone. Our results suggest that BMSCs can attenuate endothelial cell damage by decreasing KYN as detected with HPLC. This method is the first to be capable of capturing functional changes in the cells and is simple, fast, and suitable for cellular level research purposes.
