Outlier ophthalmologists in the treatment of neovascular age-related macular degeneration with intravitreal therapy.
Article in The British journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTo compare individual ophthalmologists grouped as outliers or non-outliers based on the mean 12-month visual acuity (VA) outcomes for their patients with neovascular age-related macular degeneration (nAMD).
methodsThis prospectively designed database study included treatment-naïve eyes with nAMD starting vascular endothelial growth factor inhibitors between July 2018 and April 2023 in Australia. Ophthalmologists were classified into high outliers, non-outliers and low outliers with a funnel plot of the adjusted mean 12-month VA change. The number of injections, last injection interval and proportion of visits where choroidal neovascularisation was active were compared between the groups.
results38 ophthalmologists who treated a total of 1266 eyes (male, 35%; mean age, 81 years old) were classified into 1 high outlier, 34 non-outliers and 3 low outliers (mean VA change, 7.5, 5.1 and 2.5 letters, respectively). The high outlier gave significantly more injections than the non-outliers (mean, 8.6 vs 7.7; p<0.001), while the low outliers administered significantly fewer injections than the non-outliers (mean, 7.1 vs 7.7; p=0.009). The last injection interval was shortest in the high outlier's eyes (9.4 weeks), followed by non-outliers' (10.8 weeks; p=0.04 (vs high outlier's)) and low outliers' (11.8 weeks; p=0.22 (vs non-outliers')). The low outliers' patients had more visits with intraretinal fluid (59%) than non-outliers' (29%; p<0.001) and high outlier's patients (31%; p<0.001).
conclusionThe low outliers' eyes had fewer injections, a longer treatment interval and more visits with intraretinal fluid. Building a system through which low outliers are anonymously notified of their performance would help improve general quality of care.
