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.

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.

Abstract

purposeThe purpose of the study is to report the long-term efficacy of patients with neovascular age-related macular degeneration (nAMD) treated with antivascular endothelial growth factor (VEGF) in Changhua Christian Hospital in Taiwan. MATERIALS AND

methodsRetrospective case series of patients with nAMD who were treated with intravitreal injection (IVI) of anti-VEGF and had a minimum follow-up of 48 months. Every patient was initially treated with three loading doses of either bevacizumab or ranibizumab, followed by a loose treat and extend regimen. Eyes were divided into two groups according to whether aflibercept was later used as a rescue therapy (Group 2) or not (Group 1). Patients underwent best-corrected visual acuity (BCVA) testing, optical coherence tomography, and ophthalmic examination at baseline and all the scheduled follow-up visits.

resultsSeventy eyes in 63 patients were included (mean age 70.54 ± 9.18 years). The mean number of IVIs per year was 5.28 ± 1.36. The mean BCVA in logarithm of the minimal angle of resolution (logMar) improved from 0.89 ± 0.45 to 0.72 ± 0.49 for all patients (

conclusionUnder a loose treat and extend protocol and rescue therapy of aflibercept, BCVA improvement was maintained for 4 years in patients with nAMD, especially in the older population (Registration Number: NCT03324542).
