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

Amebiasis, caused by intestinal infection with Entamoeba histolytica, is one of the leading causes of parasite infection-related mortality and morbidity globally. Although its pathogenesis, including determinant factors of infection outcome, remains unclear, recent clinical data indicate that the gut microbiome plays a role in determining the severity of amebiasis. Recently, we investigated the effects of the gut microbiome on neutrophil mediated protection from E. histolytica infection using a mouse model. We identified that surface expression of CXCR2 on neutrophils was diminished in mice with dysbiosis, which resulted in decreased neutrophil recruitment to the infection site, allowing more aggressive intestinal tissue damage by E. histolytica. Our results indicated that oxidase activity during E. histolytica infection was also diminished after dysbiosis, consistent with the results from prior research. Thus, the gut microbiome plays an important role in regulating neutrophil phenotype when fighting against external pathogens.
