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

Adipose tissue remodelling is considered a critical pathophysiological hallmark of obesity and related metabolic diseases. Berberine (BBR), a natural isoquinoline alkaloid, has potent anti-hyperlipidaemic and anti-hyperglycaemic effects. This study aimed to explore the role of BBR in modulating adipose tissue remodelling and the underlying mechanisms. BBR protected high fat diet (HFD)-fed mice against adiposity, insulin resistance and hyperlipidemia. BBR alleviated adipose tissue inflammation and fibrosis by inhibiting macrophage infiltration, pro-inflammatory macrophage polarization and the abnormal deposition of extracellular matrix, and the effect was mediated by BBR directly binding and activating the deacetylase Sirtuin 3 (SIRT3) and suppressing the activation of the mitogen-activated protein kinases and nuclear factor-κB signalling pathways. Furthermore, BBR decreased microRNA-155-5p secretion by macrophages, which in turn ameliorated liver injury. Moreover, BBR mitigated inflammatory responses in both LPS-stimulated macrophages and TNF-α-treated adipocytes and suppressed macrophage migration towards adipocytes by activating SIRT3. Collectively, this study revealed that BBR improved adipose tissue remodelling, and subsequently inhibited the secretion of microRNA-155-5p by macrophages, which alleviated adiposity, insulin resistance and liver injury in obese mice. The modulation of adipose tissue remodelling by activating SIRT3 could contribute to the anti-hyperlipidemic and anti-hyperglycemic effects of BBR.
