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

backgroundTo study the effect of anti-VEGFs in proliferative MacTel 2

methodsSixty-four eyes of 51 patients of MacTel 2 with subretinal neovascular membrane (SRNVM) undergoing intravitreal anti-VEGF monotherapy at our institution between January 2015 and December 2018 were evaluated for visual acuity, central macular thickness (CMT) and total macular volume (TMV) using optical coherence tomography (OCT). Repeat investigations were performed at the final follow-up.

resultsLocation of SRNVM was foveal (F) in 65.6% eyes and extrafoveal (EF) in 34.4% eyes. Both CMT and TMV were lower significantly at baseline in EF-SRNVM. Fifty-six eyes received intravitreal bevacizumab and 8 eyes received ranibizumab. Average 2.14 ± 1.21 injections (range, 1-6) were administered. After a mean follow-up duration of 16.01 ± 12.96 months, the final visual acuity (VA) improved in 35.9% eyes, reduced in 28.1% and remained unchanged in 35.9% eyes. Significant improvement of VA was seen in F-SRNVM; however, overall, there was no significant improvement in visual acuity. Significant reduction in CMT was seen in F-SRNVM from 391.73 ± 152.45 μm to 293.33 ± 114.77 μm (p < 0.05) while EF-SRNVM did not show significant reduction. Total macular volume overall changed significantly from 8.79 ± 1.69 to 8.05 ± 1.27 (p < 0.05) and individually in F- and EF-SRNVM (p < 0.05). Intravitreal bevacizumab and ranibizumab monotherapy both had similar efficacy.

conclusionsAnti-VEGF agents can be successfully used to treat proliferative MacTels. Macular volume measurement on OCT may be a useful parameter for evaluating EF-SRNVM and as a prognostic marker of management outcomes.
