Changes of focal macular and full-field electroretinograms after intravitreal aflibercept in patients with central retinal vein occlusion.
Article in Documenta ophthalmologica. Advances in ophthalmology, 2020. 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
purposeTo evaluate the physiology of the macular and whole retina after intravitreal aflibercept (IVAs) injections in patients with macular edema associated with a central retinal vein occlusion (CRVO) by electroretinography (ERG).
methodsWe studied 20 eyes of 20 patients with non-ischemic CRVO (72.0 ± 9.2 years). All patients were treated with monthly injections of IVA for the initial 3 months and then treated by the treat-and-extend (TAE) regimen for 12 months. The best-corrected visual acuity (BCVA), optical coherence tomographic images, focal macular ERGs (fmERGs), and full-field ERGs recorded before and after the treatment were compared. The fmERGs were elicited by a 15° white stimulus spot centered on the fovea. The full-field ERGs were recorded by a protocol recommended by International Society for Clinical Electrophysiology of Vision. The amplitudes and implicit times determined before and after the IVA were compared.
resultsThe foveal thickness was significantly reduced accompanied by improvement of the BCVA after the treatments, and the improvements were maintained for at least 12 months. The amplitudes and implicit times of the fmERGs improved continuously for the 12 months. On the other hand, the reduced amplitudes of the full-field ERG, summed oscillatory potentials, and the photopic negative responses remained unchanged for the 12-month period. However, the implicit times of the maximum and cone responses were significantly shortened after the IVA.
conclusionsIVA injections by the TAE regimen led to a continuous improvement of the macular function in patients with ME associated with a CRVO. However, the function of the whole retina changed differently than the macula after the treatment.
