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 muscle-specific protein NRAP is concentrated at cardiac intercalated disks, plays a role in myofibril assembly, and is upregulated early in mouse models of dilated cardiomyopathy. Using a tet-off system, we developed novel transgenic lines exhibiting cardiac-specific NRAP overexpression ~2.5 times greater than normal. At 40-50 weeks, NRAP overexpression resulted in dilation and decreased ejection fraction in the right ventricle, with little effect on the left ventricle. Expression of transcripts encoding brain natriuretic peptide and skeletal α-actin was increased by cardiac-specific NRAP overexpression, indicative of a cardiomyopathic response. NRAP overexpression did not alter the levels or organization of N-cadherin and connexin-43. The results show that chronic NRAP overexpression in the mouse leads to right ventricular cardiomyopathy by 10 months, but that the early NRAP upregulation previously observed in some mouse models of dilated cardiomyopathy is unlikely to account for the remodeling of intercalated disks and left ventricular dysfunction observed in those cases.
