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

We investigated the efficacy of intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents in branch retinal vein occlusion (BRVO). Databases, including PubMed, EMBASE, and the Cochrane Library, were searched on November 11, 2022. Studies comparing the pro-re-nata (PRN) regimen after the first treatment (PRN group) to three consecutive monthly injection regimens followed by the PRN regimen (3 + PRN group) were investigated. The primary outcomes were the change in best-corrected visual acuity (BCVA) and the change in central retinal thickness (CRT), with the secondary outcome being the injection frequency. Among 195 reports on anti-VEGF treatment, six comparative studies were included in this meta-analysis. The two groups had no statistically significant differences in terms of BCVA or CRT. However, the total number of injections during follow-up was significantly lower in the PRN group than in the 3 + PRN group (95% CI - 2.09 to - 0.83). The as-needed injection regimen is as effective as 3-monthly loading in terms of anatomical and functional improvement for BRVO, along with a lower treatment burden for patients and physicians.
