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

aimTo explore the efficacy of conbercept after switching from bevacizumab/ranibizumab in eyes of central retinal vein occlusion (CRVO) through optical coherence tomography angiography (OCTA).

methodsPatients with prior treatment of a minimum of three consecutive intravitreal injections of either bevacizumab or ranibizumab, followed by injection of conbercept, were recruited. The minimal follow-up period after switching was 12mo. Central retinal thickness (CRT), best-corrected visual acuity (BCVA), the interval of injections was reviewed. Perfusion density (PD) and vascular length density (VLD) of superficial and deep capillary plexus were acquired from OCTA images before and after switching.

resultsTwenty-four eyes were included. CRT significantly decreased from 460.71±153.23 µm (before switching) to 283.92±38.27 µm at the end of follow-up (

conclusionIn cases of refractory macular edema secondary to CRVO, switching to conbercept improves macular thickness and extends interval of injection. Retinal microvasculature cannot improve with treatment of conbercept.
