A new characterization for nonarteritic anterior ischemic optic neuropathy.
Article in International journal of clinical and experimental medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
This study is to investigate the clinical characteristics of patients with nonarteritic anterior ischemic optic neuropathy (NAION). Totally 133 patients (156 eyes) were included in this study. At the first visit and follow-up visits, the patients were subjected to the ophthalmic evaluations, including the fundus photography, visual field (VF) test, fluorescein fundus angiography, and optical coherence tomography (OCT). The visual acuity (VA) of 156 eyes and the VF of 148 eyes were evaluated. For the VA assessment, 59 (38%), 67 (43%), and 30 (19%) cases presented with an initial VA ≥ 20/40, between 20/40 and 20/400, and ≤ 20/400, respectively. VA was improved in 44% and deteriorated in 8% of the patients with VA < 20/20 after NAION onset. Inferior or superior altitudinal defects, constricted fields, and nasal steps were the most common VF defects. In the eyes with VF defects, 32 cases (22%) were improved, and 25 cases (17%) were worsened. In the 61 cases (39%) with VA ≤ 20/200 at NAION onset, neuroepithelial detachment in the fovea was found in 37 eyes (61%). For the optic disc assessment, retinal nerve fiber layer (RNFL) thickening was the most common symptom of NAION. Out of the 36 eyes with ONA or DR, 72% showed VA improvement after the NAION occurrence in the contralateral eye. Poor microcirculation perfusion in the bilateral optic nerve hypoplasia (ONH) might be the underlying mechanism for NAION, which could be relieved by compromising the blood supply to the one side.
