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

introductionAnti-vascular endothelial growth factors (anti-VEGFs) are considered standard of care therapy for diabetic macular oedema (DME). This study examined treatment patterns and outcomes in patients with DME treated with anti-VEGF therapy.

methodsUsing anonymized electronic medical record data collected from three UK sites, this retrospective cohort study assessed rates of anti-VEGF intravitreal injections in adults with treatment-naïve DME who received their first treatment between 1 September 2010 and 31 July 2018. The proportion of patients with at least one interval of at least 12 weeks between injections; the distribution of injection intervals; the discontinuation rates; and the number of anti-VEGF injection-, injection-free- and total visits were assessed during the first and second years of treatment.

resultsOverall, 1606 patient eyes with DME were included, with no minimum follow-up. During the first and second year of treatment, 63.2% and 73.1% of eyes had at least one anti-VEGF injection interval of at least 12 weeks, respectively. In the first and second years of treatment, the mean (standard deviation) numbers of injections were 7.7 (1.9) and 5.6 (2.2), with 14.2 (5.7) and 13.4 (6.4) total clinic visits, and 6.6 (5.0) and 7.8 (5.8) injection-free visits, respectively. In total, 27.8% of patient eyes discontinued treatment during the first 2 years.

conclusionsThe high number of clinic visits and high discontinuation rates demonstrate a significant unmet need for a treatment to enable sustainable extended injection intervals, while maintaining visual acuity. This could improve patient adherence and health-related quality of life for patients with DME.
