Changes in metamorphopsia following intravitreal aflibercept injection for diabetic macular edema.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The aim of the present study was to investigate changes in metamorphopsia in patients with diabetic macular edema (DME) following intravitreal aflibercept injection (IVA) with the treat and extend (TAE) regimen for a year. We performed a post hoc analysis of a multicenter, open-label, single-arm, prospective study. The study included 20 patients with DME. All eyes received 3 monthly loading injections of 2 mg aflibercept, followed by a TAE regimen. Every visit, the severity of metamorphopsia and the best-corrected visual acuity (BCVA) were evaluated, and optical coherence tomography (OCT) images were obtained. The severity of metamorphopsia was measured using M-CHARTS. The metamorphopsia scores before treatment and at 1, 2, 3, 6 and 12 months following treatment were 0.25 ± 0.23, 0.21 ± 0.15, 0.19 ± 0.23, 0.14 ± 0.16, 0.17 ± 0.20 and 0.10 ± 0.17, respectively, with significant improvement from before treatment to 3 and 12 months following treatment (p < 0.05 and p < 0.005, respectively). At the time of macular edema resolution, the presence of an epiretinal membrane (ERM) was associated with the metamorphopsia score (p < 0.05). In conclusion, the metamorphopsia score in patients with DME improved following IVA with the TAE regimen for one year. The presence of ERM was associated with the metamorphopsia score.
