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

purposeTo investigate the pathogenesis of diffuse diabetic maculae edema (DME).

methodsInternal limiting membrane (ILM) specimens were surgically peeled from 16 eyes of 15 patients with diffuse DME (diabetic retinopathy (DR) group) and from 12 eyes of 12 patients without diabetes (non-DR group). The specimens were then examined by light microscopy (LM), transmission electron microscopy (TEM), and immunohistochemistry.

resultsExamination by LM revealed numerous cells on the inner surface of the ILM specimens in the DR-group, among which five different cell types (glial cell, fibroblast-like cell, macrophages, neutrophils, and lymphocytes) were confirmed. Examination by TEM revealed that the thickness of the peeled ILMs in the DR group was significantly greater, and four types of cellular element (glial, fibroblast-like, macrophages, and lymphocytes) were confirmed on the surface of the vitreous side of the specimens. The existence of glial cells and macrophages was confirmed by immunohistochemistry.

conclusionsIn diffuse DME, the ILM is thickened and a variety of cellular elements, especially numerous kinds of inflammatory cell, adhere to the inner surface of the ILM. To attenuate diffuse DME, vitrectomy combined with ILM peeling to remove the inflammatory cells and the physical barrier might be effective.
