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
Purpose: To report a rare case of an anteriorly enlarged giant bleb following Ahmed ClearPath 350 glaucoma drainage device implantation, successfully treated with compression sutures. Observations: A 50-year-old man with a history of primary open angle glaucoma and multiple prior glaucoma procedures presented with a progressively enlarging inferonasal conjunctival bleb in the right eye, six months after Ahmed ClearPath 350 implantation. Examination revealed visual acuity (VA) of 20/40, intraocular pressure (IOP) of 6 mmHg, and a large, elevated, fluid-filled conjunctival bleb. While bleb formation is a desired outcome following glaucoma drainage device (GDD) implantation and trabeculectomy, the increasingly large size of this bleb caused discomfort, worsening vision, and difficulty closing the eye. Due to its rare nature, there was little consensus available regarding treatment. Compression sutures were placed in attempt to flatten the bleb. At one-week follow-up, vision and discomfort improved and slit-lamp examination revealed a markedly flatter bleb. Sutures were sequentially removed via slit-lamp during the one-month and two-month postoperative visits. At one-year follow-up, VA was 20/25, IOP was 6 mmHg, and slit lamp examination revealed a completely flattened inferonasal bleb. Conclusions and importance: This case highlights a rare presentation of a giant inferonasal conjunctival bleb developing several months after Ahmed ClearPath 350 implantation. The successful use of compression sutures suggests they may be a viable treatment option for similar post-GDD implantation bleb complications.
