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

BACKGROUND &

aimsHigh-fat diet (HFD) feeding is associated with gastrointestinal motility disorders. We recently reported delayed colonic motility in mice fed a HFD mice for 11 weeks. In this study, we investigated the contributing role of gut microbiota in HFD-induced gut dysmotility.

methodsMale C57BL/6 mice were fed a HFD (60% kcal fat) or a regular/control diet (RD) (18% kcal fat) for 13 weeks. Serum and fecal endotoxin levels were measured, and relative amounts of specific gut bacteria in the feces assessed by real time PCR. Intestinal transit was measured by fluorescent-labeled marker and bead expulsion test. Enteric neurons were assessed by immunostaining. Oligofructose (OFS) supplementation with RD or HFD for 5 weeks was also studied.

resultsHFD-fed mice had reduced numbers of enteric nitrergic neurons and exhibited delayed gastrointestinal transit compared to RD-fed mice. HFD-fed mice had higher fecal Firmicutes and

conclusionsTogether our data suggest that intestinal dysbiosis in HFD fed mice contribute to the delayed intestinal motility by inducing a TLR4-dependant neuronal loss. Manipulation of gut microbiota with OFS improved intestinal motility in HFD mice.
