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

Background Hypertensive myocardial fibrosis (MF) is characterized by excessive deposition of extracellular matrix and cardiac fibroblast proliferation, which can lead to heart failure, malignant arrhythmia, and sudden death. In recent years, with the deepening of research, microRNAs have been found to have an important role in blood pressure control and maintaining normal ventricular structure and function. Methods and Results In this study, we first documented the downregulation of microRNA-26a (miR-26a) in the plasma and myocardium of spontaneously hypertensive rats; more importantly, miR-26a-deficient mice showed MF, whereas overexpression of miR-26a significantly prevented elevated blood pressure and inhibited MF in vivo and angiotensin II-induced fibrogenesis in cardiac fibroblasts by directly targeting connective tissue growth factor and Smad4. miR-26a inhibited cardiac fibroblast proliferation by the enhancer of zeste homolog 2/p21 pathway. Conclusions Our study identified a novel role for miR-26a in blood pressure control and hypertensive MF and provides a possible treatment strategy for miR-26a to alleviate and reverse hypertensive MF.
