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
backgroundIn the rat sepsis model, the protective effect of dexmedetomidine (Dex) in sepsis-induced tissue injuries by reducing inflammation is still unclear, and research is ongoing to determine whether Dex modulates sepsis-induced tissue injury. To investigate the effect of Dex on liver injury in sepsis rats histopathologically and immunohistochemically.
methodsIn this study, sepsis was induced in rats by 10 ml/kg E. coli injection and the protective efficacy of Dex against liver damage was investigated with histopathological and immunohistochemical findings by intraperitoneal administration of 100 mcg/kg Dex.
resultsIn our results, the most striking and basic morphological changes in the liver tissues of sepsis group rats were neutrophil leukocyte infiltrations in and around the vessels. In Dex-treated groups, neutrophil leucocyte infiltrations were more prominent and marked dilatations were observed in the vessels. The fact that inflammatory reactions were more prominent in the Dex-treated groups was thought to be related to the increase in vascular permeability due to Dex's vasodilation effect.
conclusionaccording to the histopathological and immunohistochemical findings obtained in the present study, we conclude that Dex did not alleviate sepsis-induced liver inflammation in a rat sepsis model.
