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
Objective: This study compared the efficacy and safety between phacotrabeculectomy (phaco-trab) and phacoemulsification combined with Kahook Dual Blade goniotomy (phaco-KDB) in patients with moderate to severe primary angle-closure glaucoma (PACG). Methods: This single-center, non-randomized retrospective cohort study included 77 eyes from 74 PACG patients with concurrent cataract, who underwent either phaco-trab (40 eyes, 39 patients) or phaco-KDB (37 eyes, 35 patients). All patients had moderate-to-severe visual field (VF) defects and were using ≥ 2 topical intraocular pressure (IOP)-lowering medications preoperatively. Changes in best-corrected visual acuity (BCVA), IOP, medication use, mean deviation (MD) progression of VF, and complications were compared between the two groups. Results: The comparable follow-up duration was 13.5 ± 4.1 months (phaco-trab) and 12.9 ± 3.9 months (phaco-KDB) ( Conclusions: Both KDB goniotomy and trabeculectomy, when combined with phacoemulsification, effectively improve visual acuity, reduce IOP, and stabilize VF in patients with moderate-to-severe PACG and concurrent cataract. Phaco-KDB is an effective
