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 evaluate cases with a retinal pigment epithelium (RPE) aperture using polarization-sensitive optical coherence tomography (PS-OCT). STUDY

designRetrospective consecutive case series.

methodsA retrospective study that included three eyes (three patients) with RPE aperture and age-related macular degeneration (AMD) evaluated at the Macular Clinic in Tokyo University Hospital. A three-dimensional dataset of depolarization information was obtained with a clinical prototype of PS-OCT.

resultsAll patients were categorized as intermediate AMD. RPE apertures were identified with PS-OCT as discontinuities of depolarization in the RPE layer of the pigment epithelial detachment (PED). A nonuniform decrease of depolarization in the RPE layer was also observed around the aperture. Two findings were observed above the aperture, intraretinal focal areas with high reflectivity and increased depolarization and subretinal bands with moderate reflectivity and low depolarization. Retinal sensitivity according to fundus microperimetry measured at 25 points was significantly associated with the degree of depolarization at the corresponding area (r-square = 0.60, p = 0.0001).

conclusionThe RPE aperture was characterized as a round discontinuity of depolarization. The findings with PS-OCT suggest atrophic changes in the overlying RPE of the PED. The degree of depolarization was associated with retinal sensitivity. The current results indicate that RPE apertures developed within the spectrum of atrophic AMD.
