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 report a case of wound neovascularization (Swan syndrome) one year after trabeculectomy favorably treated with two intravitreal ranibizumab injections. OBSERVATIONS: A 79-year-old woman under coumadin treatment for atrial fibrillation experienced relapsing decreased vision in her left eye due to vitreous hemorrhage. She had had a past history of ocular hypertension corneal decompensation after phacoemulsification that required a Descemet Membrane Endothelial Keratoplasty and a subsequent trabeculectomy. After clearance of the hemorrhage, examination showed neovascularization not in the retina but surrounding the sclerostomy wound of the trabeculectomy, being diagnosed as a Swan syndrome. After two intravitreal injections of ranibizumab, gonioscopy showed complete resolution of the new vessels. No further recurrences have been reported and IOP has remained controlled without glaucomatous changes 7 months after the last injection. Clinical features and patient characteristics are described. CONCLUSION AND IMPORTANCE: Anti-vascular endothelial growth factor intravitreal injections may be a good and safe alternative to manage vitreous hemorrhage secondary to wound neovascularization of the trabeculectomy site.
