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

Cardiomyocytes depend on local translation for growth and can undergo directed growth in length or width in response to different stimuli. Protein synthesis is augmented during concentric hypertrophy, which leads to thickening of the heart muscle by increasing cardiomyocyte width. Protein synthesis is controlled at the translation initiation step, when ribosome loading onto transcripts is regulated by the sequential phosphorylation of the eukaryotic initiation factor 4E-binding protein 1 (4EBP1). Here, we identified a mode of 4EBP1 phosphorylation that was associated with concentric hypertrophy in cultured cardiomyocytes and mouse hearts. Whereas canonical phosphorylation of 4EBP1 by mTORC1 regulates global protein synthesis rates, mTORC1- and nuclear ERK-dependent phosphorylation of 4EBP1 was specifically activated during concentric but not eccentric hypertrophy. Nuclear ERK-dependent phosphorylation of 4EBP1 at Ser
