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.
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
backgroundMicroRNA-21 (miR-21) is related to hypertension and cardiac remodelling. Left atrium (LA) dilation is highly sensitive to small haemodynamic changes in the left ventricle (LV) that are induced by hypertension. This study aimed to elucidate the relationship between miR-21 expression and LA dilation in elderly patients with essential hypertension (EH).
methodsIn this cross-sectional study, one hundred elderly patients with EH were recruited for the study. According to their left atrium diameters (LADs), the patients were divided into the LA dilation group [42 patients (42%)] and the no-LA dilation group [58 patients (58%)]. The serum levels of miR-21 and chemical biomarkers used in the clinic, such as creatinine, blood urea nitrogen, uric acid, fasting blood glucose, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), very-low-density lipoprotein cholesterol, Lp(a), apolipoprotein A1 (apoA1), and apolipoprotein B, were measured. All the patients underwent echocardiographic examination, and the LAD, interventricular septum (IVS), right atrium diameter (RAD), right ventricle diameter (RVD), left ventricular end-systolic diameter (LVESD), left ventricular end-systolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) were measured.
resultsThe levels of miR-21 [8.02 (5.21, 14.39)
conclusionsCirculating serum levels of miR-21 are increased in elderly patients with EH with LA dilation. miR-21 levels are significantly correlated with LA dilation in elderly patients with EH, and miR-21 may be a factor related to the clinical pathophysiological occurrence of and treatment for the progression of hypertension-related early heart damage in EH patients.
