1 · What the graph read from it

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.

2 · The registry

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

Epilepsy is a common nervous system disease, and the existing theory does not fully clarify its pathogenesis. Recent research suggests that intestinal microbes may be involved in the development of epilepsy, but which microbe is involved remains unclear. We used 16s rRNA sequencing to identify the most relevant gut microbe. To determine the relationship between this microbe and epilepsy, we used an animal model. In addition, western blotting and immunofluorescence, as well as inhibitor studies, were used to evaluate and confirm the role of microglia in this process. In this study, we first report an increase in gut Klebsiella pneumoniae in patients with epilepsy. Subsequently, animal studies revealed that Klebsiella pneumoniae in the intestinal tract affects seizure susceptibility and activates microglial cells to release inflammatory factors. Furthermore, the inflammatory response of microglial cells plays a protective role in the seizure susceptibility caused by an increased abundance of Klebsiella pneumoniae. Our results suggest that gut disruption may be involved in seizure regulation and microglia protect the brain against seizure under this condition. These findings provide a new perspective for research on the pathogenesis and prevention of epilepsy.
