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

Brown adipose tissue has been extensively studied in the last decade for its potential to counteract the obesity pandemic. However, the paracrine regulation within brown tissue is largely unknown. Here, we show that local acetate directly inhibits brown fat thermogenesis, without changing acetate levels in the circulation. We demonstrate that modulating acetate within brown tissue at physiological levels blunts its function and systemically decreases energy expenditure. Using a series of transcriptomic analyses, we identified genes related to the tricarboxylic acid cycle and brown adipocyte formation, which are down-regulated upon local acetate administration. Overall, these findings demonstrate that local acetate inhibits brown fat function.
