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

At species-specific times in embryonic development, the pro-epicardial organ appears as an outcropping of the mesothelial body wall, near the sinus venosus-liver region. The pro-epicardial vesicles attach to the myocardium, flatten, and join to form the epicardium. The epicardium shows epithelial-mesenchymal transformation: cells detach from the epithelium, fill the subepicardial space, and invade the heart tube. Epicardium-derived cells migrate as far as the core of the endocardial cushions, which differentiate into the atrioventricular valve leaflets. In the cardiac wall, other epicardium-derived cells differentiate into interstitial fibroblasts and adventitial and smooth muscle cells of the coronary arteries. Using neural crest tracings in mouse embryos (Wnt1-Cre-lacZ), we studied the patterning of cardiac neural crest cells during development. Participation of neural crest cells in the formation of the vascular media could not be excluded, although epicardium-derived cells have hitherto been considered responsible for formation of the coronary arterial smooth muscle cells. The endothelial cells of the coronary network derive mostly from the endothelium of the sinus venosus-liver region by vasculogenesis and angiogenesis. However, an epicardium-derived cell origin of some endothelial cells cannot be ruled out. The coronary vasculature is closely related to the differentiating Purkinje network, but isolated epicardium-derived cells are also associated with Purkinje cells. After ablating the pro-epicardial organ in quail embryos, we found severe malformations in the myocardial architecture, leading to the hypothesis that epicardium-derived cells give instructive signals to the myocardium for proper differentiation of the compact and the trabeculated compartments.
