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

Epigallocatechin-3-gallate (EGCG) is a primary bioactive phytochemical in green tea. Its therapeutic potential in metabolic diseases has been reported; however, the molecular mechanisms of the anti-obesity effect of EGCG have not been fully elucidated. In this study, we examined the effects of EGCG on lipid metabolism and autophagy in adipose tissue. After 8 weeks of high-fat diet feeding, mice were treated with EGCG (20 mg/kg/day) for 2 weeks to test in vivo anti-obesity effects of EGCG. EGCG treatment improved glucose tolerance and caused body weight loss. Interestingly, reduced adipose tissue mass was more prominent in visceral compared to subcutaneous white adipose tissue. Mechanistically, EGCG treatment increased autophagic flux in white adipose tissue through the AMP-activated protein kinase-mediated signaling pathway. Adipocyte-specific knockout of Beclin1 mitigated the effects of EGCG on visceral adipose tissue mass and glucose tolerance, indicating that the anti-obesity effect of EGCG requires Beclin1-dependent autophagy. Collectively, our data demonstrated that EGCG has anti-obesity effects through the upregulation of Beclin1-dependent autophagy and lipid catabolism in white adipose tissue (WAT).
