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

backgroundStickler syndrome causes ocular abnormalities, including retinal detachment and vitreoretinal degeneration, and systemic anomalies such as arthritis and deafness. Although retinal detachment is characteristic of this syndrome, the pathogenesis is unknown. CASE REPORT: A 10-year-old boy reported decreased vision and presented 5 days after visual loss.

resultsOphthalmoscopy showed a retinal detachment with a giant tear in the right eye, and a nonpigmented epithelial detachment with pars plicata breaks in the left eye. Bilateral findings included an empty vitreous and a vitreous membrane at the equator. The systemic abnormalities included short stature and joint hypermobility. The diagnosis was type 1 Stickler syndrome, and the eyes were treated surgically. Immunohistochemistry showed that the vitreous membrane resected intraoperatively was comprised primarily of Müller cells. Electron microscopy showed dense collagen fibers around the cells in the membrane that were identical to the vitreous collagen inserted into the basement membrane of the cells, which was similar to the ultrastructure of the vitreous base.

conclusionMüller cells might be primary components of the vitreous membrane in type 1 Stickler syndrome. The vitreoretinal interface, which resembled the ectopic vitreous base, in the vitreous membrane may be related to the pathogenesis of the retinal detachment.
