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

Neuroinflammation, defined as the induction of immune-related processes within the central nervous system, is recognized as a component of many neurodegenerative disorders, including glaucomatous degeneration of retinal ganglion cells (RGCs). Previous work in vitro identified IL-6 as a potential neuroprotective factor for RGCs, particularly those challenged by glaucoma-related stressors. Here we examined the temporal and spatial characteristics of IL-6 signaling in response to two stressors related to RGC neurodegeneration: age and elevated intraocular pressure (IOP). Using ELISA, immunoblotting, immunolabeling and quantitative microscopy, we measured and compared whole retina and RGC-related expression of IL-6 and IL-6Rα in normal retina (young C57), retina susceptible to glaucomatous neurodegeneration (young DBA/2), aging retina (aged C57) and aging retina challenged by elevated IOP (aged DBA/2). We found that: 1) neurodegenerative stressors induce alterations in whole retina expression of IL-6 and IL-6Rα, 2) these whole retina changes do not reflect the immediate milieu of RGCs, where IL-6 and IL-6Rα expression is spatially variable and 3) the extent and magnitude of this spatial variability is stressor-dependent. Our data provide the first evidence that neurodegenerative stressors produce microenvironments of IL-6 signaling in retina and that the nature and magnitude of spatial regulation is dependent on the identity of the stressor.
