Ahmed glaucoma valve implantation with and without subconjunctival bevacizumab in refractory glaucoma.
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 4 papers, 3 of them syntheses 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 evaluate the effects of subconjunctival bevacizumab injection on intraocular pressure (IOP), hypertensive phase, and failure and success rates of Ahmed Glaucoma Valve (AGV) implantation.
methodsA total of 63 eyes of 63 patients (30 cases in control and 33 cases in bevacizumab group) were included in this randomized masked prospective clinical trial. Pre- and postoperative BCVA, IOP, number of medications, complications and success rates were compared between AGV + bevacizumab and AGV alone group.
resultsBoth groups showed statistically significant reductions in IOP in all their follow-up visits (P < 0.05). The mean IOP was lower in the AGV + Bevacizumab group than AGV group in all follow-up visits. However, the difference was only significant at the 3rd month (17.3 ± 6.2 vs. 20.7 ± 4.6, p = 0.04). The number of medications was not differed significantly between the two groups at their last visit (p value = 0.84) Complete success rate was higher in AGV + Bevacizumab. However, the difference was not significant (p = 0.73). The qualified and overall success rate, failure rate and the need for second tube were not statistically different between the two groups. The hypertensive phase was not statistically significant between the 2 groups (33.3% in AGV + Bevacizumab group and 50% in AGV group, p = 0.06)
conclusionAdjunctive use of Bevacizumab during AGV implantation is beneficial in controlling hypertensive phase and IOP control and may lead to higher success rates and lower failure rates after AGV implantation. However, whether it's clearly beneficial or its exact role remains to be investigated.
