Clinical Use of Dexamethasone Implants in Resistant Macular Edema Secondary to Branch Retinal Vascular Occlusion Compared with Intravitreal Anti-Vascular Endothelial Growth Factor.
Article in Beyoglu eye journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectivesBranch retinal vein occlusion (BRVO) is the second most common type of retinal vascular disorder. Both inflammation and increased vascular endothelial growth factor (VEGF) levels play important roles in the pathogenesis of macular edema (ME) secondary to BRVO. The aim of this study was to compare the efficacy of 0.7-mg intravitreal dexamethasone implants with continued anti-VEGF treatment in patients with ME secondary to BRVO who were poor responders to at least 6 previous anti-VEGF injections.
methodsPatients exhibiting an insufficient response to at least 6 ranibizumab treatments and who subsequently underwent a dexamethasone implant were included Group 1. Patients who were at risk for cataract or glaucoma continued treatment with the same drug and were defined as Group 2. The best corrected visual acuity (BCVA) and central macular thickness (CMT) changes at month 2, 4, and 6 were measured.
resultsNinety eyes were evaluated. In Group 1, the mean baseline BCVA of 0.71±0.75 logarithm of the minimum angle of resolution (logMAR) improved to 0.53±0.62 logMAR at month 2 (p<.001), 0.67±0.72 logMAR at month 4 (p=0.325), and 1.03±0.83 logMAR at month 6 (p=.001). In Group 2, the mean baseline BCVA was 0.73±0.83 logMAR, and improved to 0.68±0.83 logMAR at month 2 (p=0.12), 0.698±0.81 logMAR at month 4 (p=0.270), and 0.76±0.80 at month 6 (p=0.546). The baseline CMT in each group was 588±176 μm and 545±165 μm, respectively (p=0.248). The mean CMT of Group 1 changed from a baseline measurement of 588±176 μm to 308±132 μm at month 2 (p<.001), 450±195 μm at month 4 (p<.001), and 510±190 μm at month 6 (p<.001). The mean CMT of Group 2 changed from a baseline value of 545±165 μm to 486±162 μm at month 2 (p<.001), 516±168 μm at month 4 (p<.001), and 528±171 μm at month 6 (p=0.037).
conclusionDexamethasone implants were a more effective treatment for patients with BRVO-related resistant ME than ranibizumab at month 2. However, this positive effect seems to decline rapidly in the long term.
