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

The rising incidence of cardiomyopathies poses a significant threat to the physical and mental health of patients. The establishment of an animal model that accurately reflects the clinicopathological characteristics of cardiomyopathy is essential for investigating its pathogenesis. In this study, a cardiomyocyte-specific Arhgef18 conditional knockout (cKO) mouse model was established with Cre/LoxP technology, and the results confirmed that the protein encoded by Arhgef18 (Rho/Rac guanine nucleotide exchange factor 18) was knocked out effectively in the myocardium of Arhgef18flox/flox; Nkx2.5-Cre (Arhgef18fl/fl cKO) mice. Compared to Arhgef18fl/fl mice, Arhgef18fl/fl cKO mice presented with slower body weight growth and no differences in survival curves. Cardiac structure and function revealed that Arhgef18fl/fl cKO mice developed biventricular enlargement, ventricular wall thinning and left-ventricular systolic dysfunction, along with increased Nppa and Nppb mRNA expression levels. Additionally, Arhgef18fl/fl cKO mice showed cardiomyocyte cytoskeletal rearrangements and cell polarity disorders. Our study results suggest that Arhgef18 cKO mice could provide an ideal animal model for the genetic investigation of cardiomyopathy.
