Various modalities for management of secondary angle closure neovascular glaucoma in diabetic eyes: 1-year comparative study.
Trial report in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
purposeTo compare outcome of 4 methods for management of angle closure neovascular glaucoma (NVG) in diabetic eyes.
methodsProspective comparative study, on 40 eyes (40 patients) with NVG. Patients were randomly assigned to group A (Trabeculectomy with MMC), B (Ahmed valve), C (Ex-Press Minishunt with MMC) or D (Diode cyclophotocoagulation). Patients were followed regularly for 1 year.
main outcome measuresintraocular pressure (IOP), best corrected visual acuity (BCVA), central foveal thickness (CFT), intraoperative bleeding, postoperative complications and 2ry intervention.
resultsPreoperative data were not significantly different between 4 groups. Postoperatively, there was significant drop in IOP in each group at each follow-up. Ahmed valve group showed least mean postoperative IOP and highest mean drop of the IOP at 1 day and 1 week postoperatively, while Ex-Press minishunt group had least mean postoperative IOP at 1 month and 3 months postoperatively. At 6 months and 1 year, there was no significant difference between 4 groups. BCVA was not significantly different between 4 groups. At 1 year, CFT was significantly lower in each of the 4 groups, and it was significantly the least in group A and highest in group D. Highest intraoperative bleeding was observed with trabeculectomy. Success rate was not significantly different among the 4 groups.
conclusionThe 4 management options showed a significant long-term effect on IOP, and on long-terms there was no significant difference between them for IOP and BCVA. Trabeculectomy showed highest incidence of intraoperative bleeding, while cyclophotocoagulation showed none.
