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

Current biomaterial strategies are typically unable to return skeletal muscle to pre-injury function following damage, resulting in permanent loss of muscle function. Recently, there has been a growing appreciation for the role of matrix viscoelasticity in regenerative processes, and here we address the hypothesis that changes in matrix viscoelasticity regulate muscle cell function. Using norbornene-modified type I collagen hydrogels with a tetrazine-based crosslinker, it is found that myoblast spreading, proliferation, and differentiation are improved on and within slow-relaxing hydrogels. However, satellite cell stemness is maintained only with soft, fast-relaxing hydrogels. This indicates that there is a direct link between the viscoelasticity of collagen-based substrates and muscle cell phenotype in vitro. Together, these studies further the understanding of the role of tissue mechanical properties in directing muscle cell function and provide a tool for guiding specific behaviors necessary for muscle regeneration.
