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
purposeTo evaluate the efficacy of radial optic neurotomy (RON) on retinal function in patients with central retinal vein occlusion (CRVO).
methodsTen eyes of 10 patients with CRVO underwent pars plana vitrectomy and RON. Standardized combined electroretinograms (ERGs) to full-field bright-flash stimuli were recorded preoperatively and, 3 months postoperatively. The best-corrected visual acuity and foveal thickness were also determined, before and 3 months postoperatively.
resultsThe mean best-corrected visual acuity and mean foveal thickness were both significantly improved after vitrectomy and RON. The mean amplitudes of a- and b-waves did not change significantly, but the mean b/a wave ratio was increased significantly after vitrectomy and RON. An improvement of the b/a ratio was observed in six eyes, however, an improvement of retinal circulation was confirmed on postoperative fluorescein angiograms in two of these six eyes.
conclusionsSignificant improvements were observed in the b/a wave ratio of the standard combined ERGs after surgery in eyes with CRVO. The improvement of retinal function was most likely due to improved oxygenation of retina caused by vitrectomy and not by RON.
