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
This study aimed to investigate the relationship between the expression and distribution of myocardial connexin 43 (Cx43) in the left ventricle and the incidence of sudden death due to hyperthyroid heart disease. Total 27 autopsy cases were selected from the Pathology Department of Medical School, Yangtze University from 2009 to 2014. The cases were divided into three groups (n=9): Experimental group, 6 males and 3 females, age range 20-57 years old, suddenly died of hyperthyroid heart disease; Hyperthyroid group, 7 males and 2 females, age range 27-63 years old; Control group, 5 males and 4 females, age range 27-49 years old. After pathological examination, Cx43 in the left ventricular muscle of each case was detected with immunohistochemical staining. In experimental group, Cx43 positive staining was found in the cytoplasm or side-side connection of ventricular myocardial cell, and the positive area and average optical density of Cx43 positive particles significantly decreased. In hyperthyroid group, average optical density of Cx43 positive particles decreased. In control group, Cx43 positive staining was found in the intercalated disc. In conclusion, the expression of myocardial Cx43 significantly decreased in sudden death patients with hyperthyroid heart disease. Our findings suggest that decreased expression of Cx43 may be related to sudden death of hyperthyroid heart disease.
