Surgical Outcomes of Baerveldt Glaucoma Implant Versus Ahmed Glaucoma Valve in Neovascular Glaucoma: A Retrospective Multicenter Study.

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
introductionThis multicenter retrospective study compared the surgical outcomes of Baerveldt glaucoma implant (BGI) surgery with those of Ahmed glaucoma valve (AGV) surgery in patients with neovascular glaucoma (NVG).
methodsThe study included patients with NVG aged ≥ 20 years who had undergone BGI (223 eyes) or AGV (146 eyes) surgery between April 1, 2012 and December 31, 2021 across 10 clinical centers in Japan. Surgical success or failure was the primary outcome measure of this study. We defined surgical failure as a reduction of < 20% in the pre-operative intraocular pressure (IOP) or criterion A (IOP > 21 mmHg), criterion B (IOP > 17 mmHg), or criterion C (IOP > 14 mmHg). In addition, we considered a requirement for re-operation, loss of light perception, and hypotony as surgical failure.
resultsThe surgical success rate of the BGI surgery group was significantly higher than that of the AGV group for criteria A (P = 0.01) and B (P = 0.01). Multivariate analysis revealed that AGV surgery showed significant associations with surgical failure for criteria A (hazard ratio, 1.74), B (hazard ratio, 1.72), and C (hazard ratio, 1.34). The overall incidence of postoperative complications was comparable between the two groups. The requirement for re-operation in the AGV surgery group was significantly higher than that in the BGI surgery group (12.3% vs. 5.8%, P = 0.03).
conclusionsBGI surgery yielded a higher success rate than AGV surgery in patients with NVG for a target IOP of < 21 or < 17 mmHg. No significant differences were observed between the two procedures in terms of the incidence of postoperative complications. Additional glaucoma surgery was required more frequently following AGV surgery. Therefore, BGI surgery may be a more suitable and efficacious option for the management of IOP in patients with neovascular glaucoma compared with AGV surgery.
