1 · What the graph read from 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.

2 · The registry

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

purposeThe aim of the present cross-sectional real-world study is to evaluate the impact of switch of anti-VEGF agent from ranibizumab to aflibercept on visual acuity, treatment frequency and retinal morphology after 12 months in eyes with ongoing chronic treatment for wet age-related macular degeneration (AMD) compared to eyes not subjected to switch of anti-VEGF agent.

methodsData was obtained retrospectively from the Swedish Macular Register, spectral-domain optical coherence tomography (OCT) images and electronic patient charts. All eyes included were treated in the same clinical setting at the Department of Ophthalmology at the county hospital of Västmanland in Västerås, Sweden.

resultsIn total, 282 and 359 eyes were included in the non-switch and switch cohorts, respectively. The cohorts were well balanced. Visual acuity remained stable during the observation period in both cohorts of eyes. The number of anti-VEGF treatments slowly declined over time in both cohorts of eyes and, consequently, the treatment intervals increased during the observation period. In eyes subjected to switch of anti-VEGF agent, planned treatment interval at 12 months was 7.6 (mean; SD 2.9) weeks compared to 6.8 (mean; SD 2.7) in the non-switch cohort (P = 0.001). OCT images demonstrated lower prevalence of intraretinal and subretinal fluid as well as pigment epithelial detachment at 12 months in eyes subjected to switch of anti-VEGF agent compared to non-switch eyes.

conclusionSwitch of anti-VEGF agent from ranibizumab to aflibercept did not affect visual function whereas improvement in retinal morphology was observed. These findings suggest a beneficial effect of switching from ranibizumab to aflibercept in eyes with ongoing chronic anti-VEGF treatment irrespective of previous response to ranibizumab. Longer follow-up is required to further evaluate the potential clinical significance of this finding.
