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
We aim to report a case of iris tissue obstructing the lumen following rotation of the Preserflo MicroShunt (PMS) and subsequent laser therapy, which restored the shunt's function. A 65-year-old man with bilateral primary open-angle glaucoma (right eye: early stage, left eye: severe stage) had suboptimal intraocular pressure (IOP) control in his left eye despite maximal medical therapy. Hence, with an uneventful operative course, PMS implantation augmented with mitomycin C (0.04%) was performed in the left eye. However, one week post-surgery, his IOP spiked to 30 mmHg, and anterior segment examination revealed that the adjacent iris tissue obstructed the lumen of the PMS. Neodymium-doped yttrium aluminum garnet and argon lasers were used to unclog the lumen and retract the iris tissue from the PMS. Following the procedures, the lumen was free from the iris tissue, and the IOP was normalized to 10 mmHg. His target IOP was achieved without any antiglaucoma medication to date. In contrast to surgical repositioning or revision, laser therapy can be done in an outpatient setting. It is an effective and less invasive method of removing or avoiding iris tissue from obstructing the lumen of the PMS. Laser therapy offers an effective and safe option for managing PMS obstruction while maintaining shunt function with minimal to no complications.
