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
PRéCIS: Treatment of acute angle-closure glaucoma with phacoemulsification combined with goniosynechialysis significantly improves patients' visual acuity and reduce intraocular pressure; the preoperative condition has minimal influence on the treatment outcome. PURPOSE: The study aimed to treat acute angle-closure glaucoma and explore the structural differences of the anterior segment as well as the influence of persistent high intraocular pressure on surgical outcomes.
methodsThis retrospective case-control study included 120 patients (122 eyes) with acute angle-closure glaucoma, divided into two groups based on intraocular pressure two hours post-drug treatment: a normotensive group (21 mmHg or below; 54 subjects/55 eyes) and a hypertensive group (> 21 mmHg; 66 patients/67 eyes). Anterior segment structures, corneal endothelial cell density, and other parameters were systematically analyzed. All patients underwent phacoemulsification combined with goniosynechialysis. Statistical analysis employed independent-samples t-tests, Mann-Whitney U tests, and Wilcoxon signed-rank tests, as appropriate.
resultsThere was no significant difference in the anterior segment structure between the two groups (P > 0.05) except for anterior chamber depth (t = -2.541, P = 0.012). Corneal endothelial cell density was significantly higher in the normotensive group than in the hypertensive group (Z = -0.399, P = 0.026).Postoperative visual acuity improved in both groups (Z = -8.663, P < 0.01), but no significant intergroup difference was observed (Z = -1.201, P = 0.23).Intraocular pressure decreased significantly in both groups (t = 25.901, P < 0.01). with a more pronounced reduction in the hypertensive group (Z = -3.387, P = 0.01).
conclusionsIn medically treated acute angle-closure glaucoma, anterior chamber depth differed significantly between the normotensive and hypertensive groups ( P = 0.012), whereas no significant differences were observed in other anterior segment parameters (P > 0.05). Following phacoemulsification combined with goniosynechialysis, both visual acuity and intraocular improved. Preoperative persistent high intraocular pressure has no significant effect on surgical outcomes.
