Ologen implant versus mitomycin-C for trabeculectomy: A meta-analysis.
Synthesis in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
aimTo evaluate the efficacy and safety of trabeculectomy (Trab) with mitomycin-C (MMC) versus Trab with implant.
methodsStudies published in different languages were retrieved by systematically searching Embase, PubMed, Cochrane library, China Biology Medicine disc, and Google Scholar from 1966 to April 2018, as well as manually examining the references of the original articles. The outcome measures of efficacy covered intraocular pressure, glaucoma medications reductions, and success rate. Safety evaluation was measured by relative ratio of complications.
resultsA total of 11 studies involving 443 participants were covered in this meta-analysis. The weighted mean difference (WMD) in the percentage of intraocular pressure (IOP) reduction (IOPR%) comparing Ologen group with MMC group was -3.69 (95% CI: -6.70 to -0.68) at 1 month, -2.69 (-5.17 to -0.21) at 3 months, -3.67 (-6.09 to -1.25)at 6 months, -3.24 (-6.08 to -0.41) at 12 months, 1.24 (-9.43 to 11.90) at 24 months, and 1.10 (-10.11 to 12.31) at 60 months, which showed that there was statistically significant difference at 1,3, 6, and12 months after the surgery. A significantly higher incidence of postsurgery hypotony (0.64 (95% Cl: 0.42 to 0.98)) and suture lysis (0.30 (95% CI: 0.10-0.93)) was observed in MMC group. However, there was no significant difference in the reduction in glaucoma medications, success rate, and incidence of other complications.Trab with 0.2 mg/mL MMC presented higher rates of complete success compared with Trab with 0.4 mg/mL MMC (P = .01).
conclusionTrab with MMC was associated with a higher IOP-lowering efficacy and a higher incidence of postsurgery hypotony and suture lysis in contrast to that of Trab with Ologen.
