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

backgroundThe interaction among the glomerular components plays an important role in the development of glomerular lesions; thus, investigation of the ultrastructural three-dimensional (3D) configuration of the human glomerular cells and extracellular matrix (ECM) is important for understanding the pathogenesis of glomerulosclerosis, especially glomerulonephritis.

methodsWe applied a new technique of serial block-face scanning electron microscopy (SBF-SEM), which helps to acquire serial electron microscopic images to reconstruct a 3D ultrastructure, to a human kidney biopsy specimen obtained from a 25-year-old woman with lupus nephritis.

resultsSBF-SEM demonstrated that the cytoplasmic processes of the podocyte penetrated into the lamina densa of the glomerular basement membrane, and was in direct contact with the cytoplasm of mesangial cells at the site of mesangial interposition.

conclusionAlthough this is a single-case observational study, SBF-SEM revealed a unique 3D configuration, suggesting a novel mechanism of direct intercellular cross-communication between podocytes and mesangial cells, aside from the presumed paracrine communication.
