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

Mouse lines with dysferlin deficiency are accepted animal models for limb girdle muscular dystrophy 2B and Miyoshi myopathy, yet slow progression of pathology prevents rapid screening of potential therapies for this disease. Our goal was to define a functional signature for skeletal muscles that lack dysferlin. Force generation and susceptibility to eccentric contractile injury measurements were performed in isolated limb muscles and the diaphragm from 10- and 36-week-old A/J and age-matched control mice. Limb muscles had normal specific force at both 10 and 36 weeks, whereas the diaphragm had significant deficits in both specific force and susceptibility to eccentric contractile injury. Membrane ruptures in the diaphragm during eccentric contractions occurred predominantly in myosin heavy chain 2A-expressing fibers. Dysferlin content did not vary significantly between wildtype muscles, suggesting that there was no correlation between disease severity and normal endogenous levels of the protein. These studies show that, unlike limb muscles, the diaphragm from the A/J mouse displays early deficits in function that may lower the age needed for evaluating potential therapies for dysferlinopathies.
