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

Basement membranes (BMs), a specialized form of extracellular matrix, underlie nearly all cell layers and provide structural support for tissues and interact with cell surface receptors to determine cell behavior. Both macromolecular composition and stiffness of the BM influence cell-BM interactions. Collagen IV is a major constituent of the BM that forms an extensively cross-linked oligomeric network. Its deficiency leads to BM mechanical instability, as observed with glomerular BM in Alport syndrome. These findings have led to the hypothesis that collagen IV and its cross-links determine BM stiffness. A sulfilimine bond (S = N) between a methionine sulfur and a lysine nitrogen cross-links collagen IV and is formed by the matrix enzyme peroxidasin. In peroxidasin knockout mice with reduced collagen IV sulfilimine cross-links, we find a reduction in renal tubular BM stiffness. Thus this work provides the first direct experimental evidence that collagen IV sulfilimine cross-links contribute to BM mechanical properties and provides a foundation for future work on the relationship of BM mechanics to cell function in renal disease.
