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.

Abstract

Imbalanced skeletal muscle mitochondrial dynamics contribute to the onset and progression of type 2 diabetes (T2D) by mechanisms that remain incompletely understood. Here, we examined the role of Mitochondrial Rho GTPase 1 (Miro1), an outer mitochondrial membrane enzyme, in regulating skeletal muscle insulin action and glucose homeostasis in type 2 diabetes (T2D). In a cross-sectional clinical study, we show that Miro1 accumulates in the skeletal muscle of patients with obesity and T2D, which was further replicated in mouse models of T2D. This accumulation is explained by inadequate insulin-mediated interaction between AKT and Miro1 at the outer mitochondrial membrane. In a randomized controlled trial (NCT02977442), we show that exercise training relieves skeletal muscle Miro1 accumulation while improving insulin sensitivity in patients with T2D. Muscle-specific Miro1 deletion improves oxidative capacity and insulin sensitivity in mice and cells. Taken together, these data support a key regulatory role for skeletal muscle Miro1 in the pathophysiology of T2D. ClinicalTrials.gov Identifier: NCT02977442.
