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 compare the outcomes of combined phacoemulsification and viscocanalostomy with versus without intrascleral implantation of Ahmed glaucoma valve (AGV) tube remnants in patients with primary open-angle glaucoma (POAG) and cataract. Methods: A randomized clinical trial involving 60 patients with cataract and POAG was carried out. The case group underwent phacoemulsification and viscocanalostomy together with intrascleral implantation of AGV tube remnants, while the control group underwent the same procedures without any implant. The two groups were compared in terms of best-corrected visual acuity (BCVA), intraocular pressure (IOP), cup-to-disc ratio, number of ocular hypotensive medications, surgical success rate, and scleral lake size. Results: Sixty patients were enrolled and equally divided into two groups. Postoperative IOP, BCVA, and cup-to-disc ratio did not differ significantly between the groups ( Conclusion: Our study found no significant difference in success rates or postoperative IOP control between combined phacoemulsification and viscocanalostomy with or without silicone implants. Although the case group demonstrated larger scleral lake dimensions on AS-OCT, this anatomical difference did not translate into superior IOP outcomes and was associated with a higher requirement for postoperative ocular hypotensive medications. The clinical significance of increased scleral lake size in the presence of an implant remains uncertain, and longer-term follow-up is warranted.
