Optic nerve infarction and post-ischemic inflammation in the rodent model of anterior ischemic optic neuropathy (rAION).
Article in Brain research, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 43 papers.
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.
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
Nonarteritic anterior ischemic optic neuropathy (NAION) results from isolated anterior optic nerve (ON)-axonal ischemia near the retina-optic nerve junction. We utilized a rodent model of NAION (rAION) to study the in vivo inflammatory response after pure axonal ischemic infarct. ON ischemia was generated using laser-coupled rose Bengal dye photoactivation, and the infarct localized using tetrazolium red and histology. ON inflammation was evaluated following infarct using extrinsic macrophage (ED1) and microglial (isolated Iba1) cell markers. In naive ONs, some ED1(+)/Iba1(+) cells, representing extrinsic macrophages, were present in intraretinal ON region, but not in the retroscleral (isolated ON) region. Numerous ED1(-)/Iba1(+) cells, likely representing intrinsic microglia, were present throughout the entire ON. One day post-stroke, slight increases in both ED1(+) and Iba1(+) cells were apparent in the eye region immediately surrounding the anterior ON. Three days post-stroke, there was marked infiltration and aggregates of ED1(+)/Iba1(+) cells, with axon structural disruption in the region of the ischemic infarct. ED1(+) and Iba1(+) cells were present in the portion of the ON surrounding the infarct, possibly representing a penumbral region similar to that seen in ischemic brain infarcts. Although ED1(+) cells decreased by 7-14 days post-stroke, large numbers of Iba1(+) cells persisted in the anterior ON. Similar to other CNS ischemic strokes, pure axonal ischemia results in the early recruitment of extrinsic macrophages to the ischemic region. Manipulation of the inflammatory response may be an important variable that could potentially improve visual outcome.
