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

Cardiomyocyte hyperplasia is the primary form of fetal heart growth, whereas this proliferative capacity is largely lost in adults across most mammalian species. The limited ability of adult cardiomyocytes to re-enter the cell cycle is a major cause of cardiac injury-induced morbidity and mortality. Here, we report that postprandial Burmese python cardiomyocytes activate cell cycle re-entry to promote persistent cardiac growth. Burmese pythons normally eat large meals infrequently, resulting in reversible cardiomyocyte hypertrophy. We found that frequent feeding of large meals amplifies the modest postprandial cardiac proliferation identified in an infrequent feeding interval. By activating
