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

Chronic atrial fibrillation was induced in goats by electrical pacing. After 9 to 23 weeks of sustained atrial fibrillation, the morphology of the atrial structures was examined. The majority of the cardiomyocytes exhibited marked changes in their cellular substructures, with the replacement of sarcomeres by glycogen as the main characteristic. Using immuno-histochemical staining procedures, we assessed the expression and organization of contractile and cytoskeletal proteins in these cases and compared them with the expression and organization of these proteins in normal atria. Part of the atrial cardiomyocytes acquired a dedifferentiated phenotype, as deduced from the re-expression of alpha-smooth muscle actin, the disappearance of cardiotin, and the staining patterns of titin, which resembled those of embryonic cardiomyocytes. From these results we conclude that chronic atrial fibrillation induces myocardial dedifferentiation. This model of chronic atrial fibrillation in goats offers the possibility to study the time course of changes in cardiac structure during sustained atrial fibrillation and after cardioversion.
