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 factors associated with macular atrophy (MA) incidence in neovascular age-related macular degeneration treated with either ranibizumab or aflibercept in an Observe-and-Plan variable dosing regimen.

methodsInformation was obtained from two identical prospective treatment protocols using ranibizumab or aflibercept in a variable dosing regimen termed "Observe and Plan." Eyes without MA at baseline were included. New atrophy at the final 2-year visit was investigated with univariate and multivariate analysis to identify associated risk factors, focusing on treatment factors.

resultsDe novo MA developed in 63 (42%) of 149 eyes/patients (mean age 79.0 years), in 70 eyes treated using aflibercept and 79 eyes using ranibizumab. The univariate analysis showed multiple associations of MA with baseline factors, of which the following were confirmed as independent risk factors after multivariate stepwise logistic regression: lower number of anti-vascular endothelial growth factors injections (P = 0.011), depigmentation (P = 0.0004), reticular pseudodrusen (P = 0.0005), lower baseline visual acuity (P = 0.0006), and retinal angiomatous proliferation (P = 0.001). The drug type showed no significant association with MA incidence (P = 0.21).

conclusionWithin the variable dosing regimen, MA incidence was higher when fewer injections were required. More injections, if required by disease activity, did not increase the risk for MA.
