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

introductionThe purpose of this study was to investigate the extent and morphology of the choriocapillaris' density defect in patients with drusen in non-neovascular age-related macular degeneration (AMD).

methodsParticipants in this study were 36 patients with non-neovascular AMD and drusen. All patients underwent best-corrected visual acuity, slit-lamp examination, spectral domain-optical coherence tomography (SD-OCT), and optical coherence tomography angiography (OCTA).

resultsIn all studied cases, the presence of drusen was associated with choriocapillaris' reduced blood flow signal of different extent and severity. Three types of choriocapillaris' non-perfusion were observed, along with an association between the size of drusen and the morphology of choriocapillaris' density defect. Moreover, the extent of choriocapillaris' density change has been related to ellipsoid zone disruption and therefore to visual impairment.

conclusionsOur study showed that in patients with drusen due to non-neovascular AMD, there is choriocapillaris' impairment of different morphology in OCTA, which is mainly related to the size and location of the drusen.
