Anti-vascular endothelial growth factor dosing frequency and visual outcomes in macular oedema following branch retinal vein occlusion.
Article in Eye (London, England), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo determine the relationship between treatment frequency with intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents and visual acuity (VA) outcomes in eyes with macular oedema (MO) secondary to branch retinal vein occlusion (BRVO) in US clinical practice.
methodsStudy eyes that initiated anti-VEGF injections between January 2012 and May 2016 were followed for ≥1 year in a retrospective analysis of medical records (Vestrum Health database). Eyes were analysed in 2 cohorts by treatment duration (years 1 and 2) and then in 2 subcohorts by injection frequency (≤6 or ≥7 injections/year).
resultsAmong 3099 eyes with MO secondary to BRVO, 1197 (38.6%) received ≤6 injections (mean injections, 4.6; baseline mean VA, 53 letters) and 1902 (61.4%) received ≥7 injections through 1 year (mean injections, 8.8; baseline mean VA, 52 letters). At year 1, mean VA gain from baseline was 10.4 versus 13.9 letters in eyes receiving ≤6 versus ≥7 injections (p < 0.001). At year 2, mean VA in eyes receiving ≤6 (n = 42) versus ≥7 injections (n = 227) was 64 versus 68 letters, respectively (p = 0.19). Mean VA change between the start and end of year 2 in eyes receiving ≥7 injections in year 1 and ≤6 in year 2 differed significantly from that of eyes receiving ≥7 injections in both years (-3.0 vs 0.7 letters, respectively; p < 0.001).
conclusionsIn routine clinical practice, more frequent dosing with anti-VEGF agents was associated with greater visual benefits in eyes with MO secondary to BRVO.
