Results of switchback from ranibizumab to aflibercept in patients with exudative age-related macular degeneration.

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
purposeIntravitreal injection of anti-VEGF drugs has become standard therapy for patients with exudative age-related macular degeneration (AMD). However, some patients do not exhibit sufficient response to the drugs for suppression of choroidal neovascularization activity. We investigated the efficacy of switchback from ranibizumab to aflibercept in patients with AMD who could not achieve further benefit beyond initial therapy of aflibercept injection.
methodsEleven eyes of eleven patients were included in this study. Two patients were nonresponders, and nine exhibited tachyphylaxis to aflibercept. All patients received three monthly injections of ranibizumab as an initial phase of switching and received aflibercept as a switchback drug. We investigated changes in injection interval, visual acuity, and central retinal thickness.
resultsIn four patients (36.4%), injection interval was extended. The interval was 6.73 weeks before switch and 9.27 weeks after switchback (
conclusionA switchback from ranibizumab to aflibercept may be beneficial in some patients with AMD who exhibit tachyphylaxis to aflibercept.
