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

introductionAcute treatment with metformin has a cardio-protective effects by suppression of inflammatory responses during myocardial infarction (MI) through activation of AMP-activated protein kinase (AMPK). Neutrophils have a pivotal role during MI-induced inflammatory responses. Some anti-inflammatory treatments have decreased cardiac injury and infarct size in MI. Here we evaluated the effects of chronic pre-treatment with metformin on myocardial remodeling and neutrophil recruitment after isoproterenol-induced MI.

methodsMale wistar rats were randomly assigned into 6 groups (n=6) of untreated control, sham, isoproterenol (Iso), and pre-treated orally with 25, 50, and 100 mg/kg of metformin, twice daily, for 14 days. Isoproterenol was injected subcutaneously (sc) at 13th and 14th days for induction of acute MI. Histopathological examinations were done on the harvested hearts. Number of neutrophils in peripheral blood and their infiltration to myocardium were evaluated by Gimsa staining and myeloperoxidase (MPO) assay, respectively.

resultsHistopathological analysis showed a significant attenuation of isoproterenol-induced cardiomyocyte necrosis and fibrosis by all three doses of metformin. The heart to body weight ratio was also decreased with all doses of metformin. Pre-treatment with metformin in comparison to Iso (MI) group reduced peripheral neutrophils (p<0.05, p<0.01, and p<0.001 at 25, 50, and 100 mg/kg; respectively) as well as MPO activity (p<0.05 and p<0.01 at 50 and 100 mg/ kg, respectively).

conclusionPre-treatment with metformin decreased post-MI myocardial injuries by reducing cardiac remodeling and myocardial neutrophil activity. The results could be explained as a new mechanism for cardio-protective effect of metformin.
