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

Currently, the weight loss effects of piperine have gained considerable attention; however, the underlying mechanism needs to be comprehensively elucidated. In the present study, we aimed to investigate the relationship between the weight loss effects of piperine and intestinal function. Based on the obtained results, piperine inhibited intestinal fatty acid absorption in both cellular and animal models. The underlying mechanism may be related to the downregulation of fatty acid absorption-related genes, fatty acid-binding protein 2 and cluster of differentiation 36, but not fatty acid transport protein 4. In addition, piperine repaired the tight junction damage induced by obesity by downregulating jejunal tumor necrosis factor-α and reducing lipopolysaccharide-induced damage on intestinal cell proliferation, thus enhancing intestinal barrier function, which is beneficial in reducing chronic inflammation associated with obesity. In conclusion, the anti-obesity effect of piperine is related to the enhancement of intestinal barrier function and inhibition of intestinal fatty acid absorption.
