Trial report in Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAim of this study is the presentation of long-term results regarding the effectiveness and safety of the implantation of Ahmed glaucoma valve (AGV) devices using a pars plana approach after vitrectomy in the treatment of therapy refractive glaucoma.
methodsThe implantation of AGV devices using a pars plana approach after vitrectomy was performed in 27 eyes of 22 patients with neovascular glaucoma (n = 7 patients), uveitis (n = 6), complex juvenile secondary glaucoma (n = 4), primary open angle glaucoma (n = 3), pseudoexfoliation glaucoma (n = 1) and nanophthalmus (n = 1). Intraocular pressure, visual acuity and subsequent complications were documented. The mean follow-up period was 23.6 months.
resultsIntraocular pressure was significantly reduced from 30.2 mmHg preoperatively to 13 mmHg after a follow-up of 36 months. The mean visual acuity did not change significantly, five eyes required a subsequent explantation of which three were due to AGV-related complications.
conclusionsThe implantation of AGV devices using a pars plana approach permits an effective and permanent reduction of intraocular pressure (IOP) even in severe therapy refractive secondary glaucoma; however, the risk of serious sight-threatening complications has to be taken into account.
