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

purposeTo investigate 6-month outcomes in eyes with neovascular age-related macular degeneration (nAMD) switched from intravitreal aflibercept 2 mg to intravitreal aflibercept 8 mg. STUDY

designRetrospective observational study.

methodsWe reviewed records of consecutive nAMD eyes switched from aflibercept 2 mg to 8 mg. In eyes continuing aflibercept 8 mg, best-corrected visual acuity (BCVA), treatment intervals, and anatomical/exudative parameters were evaluated at 6 months. In eyes that could not continue, reasons for discontinuation were examined.

resultsForty-four eyes from 44 patients were included. At 6 months, 35 eyes (79.5%) continued and 9 (20.5%) discontinued aflibercept 8 mg. Discontinuing eyes had significantly shorter pre-switch treatment intervals and more frequent prior therapies than continuing eyes. In the continuation group, BCVA remained stable (median 0.05 to 0.00 logMAR, P = 0.351), while the treatment interval was significantly extended (median 7.0 to 9.0 weeks, P < 0.001). Central retinal thickness and pigment epithelial detachment height decreased significantly (P = 0.035 and P = 0.021, respectively). The proportion of eyes with subretinal fluid significantly decreased from 74.3 to 37.1% (P = 0.003). Of the discontinuations, 4 were due to worsening exudation and 5 to inability to extend to ≥8 weeks as required by labeling. No intraocular inflammation or serious adverse events occurred.

conclusionsSwitching to aflibercept 8 mg achieved anatomical improvements and longer treatment intervals in ~80% of nAMD cases, suggesting it may be a useful alternative to aflibercept 2 mg. However, continuation may be difficult in refractory cases requiring frequent injections before switching.
