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

MOTS-c is an exercise mimetic and improves insulin sensitivity in aged and diet-induced obese mice. Although plasma markers are good markers for the metabolic condition, whether MOTS-c changes plasma markers in diet-induced obese mice has not been examined. Here, we used an unbiased metabolomics approach to examine the effect of MOTS-c on plasma markers of metabolic dysfunction. We found that three pathways - sphingolipid metabolism, monoacylglycerol metabolism, and dicarboxylate metabolism - were reduced in MOTS-c-injected mice. Interestingly, these pathways are upregulated in obese and T2D models. MOTS-c improves insulin sensitivity and increases beta-oxidation to prevent fat accumulation in DIO mice through these pathways. These results provide us a better understanding of the mechanism of how MOTS-c improves insulin sensitivity and reduces the body weight and fatty liver and opens a new venue for further study.
