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

Mesenchymal stem cells (MSCs) have been shown to attenuate myocardial fibrosis after myocardial infarction by secreting various bioactive molecules that positively affect the failing heart. We hypothesized that serum factors play an active role in the activation of bone marrow MSCs after myocardial infarction and explored the effect of differential exocytosis on cardiac repair after infarct serum preconditioning by examining whether exosomes derived from MSCs have a positive effect on cardiac fibrosis. Bone marrow MSCs were pretreated by collecting rat myocardial infarction serum, followed by the collection of myocardial infarction serum exosomes (MIS-EXO). In vivo, intramyocardial injection of exosomes was performed 30 min after permanent ligation of the anterior descending branches of Sprague Dawley rats, and echocardiography was performed at different time intervals to evaluate cardiac function. Hearts were sampled 4 weeks later, and the degree of myocardial fibrosis and inflammatory response were evaluated using hematoxylin and eosin and Masson's trichrome staining. Treatment with common culture-derived exosomes (CON-EXO) improved cardiac function and myocardial fibrosis after myocardial infarction in rats compared with the myocardial infarction group. In vitro, the antifibrotic effects of different exosomes on tumor growth factor-β-induced fibroblast fibrosis model were assessed by protein blotting, qPCR, and immunofluorescence. Compared with CON-EXO, MIS-EXO exerted superior therapeutic effects in terms of anti-inflammation, improvement of left ventricular function, and reduction of fibrosis. Infarct serum pretreatment with bone marrow mesenchymal stem cell-derived exosomes enhances the anti-cardiac fibrosis effect in rats after myocardial infarction.
