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

purposeThe purpose of this article is to investigate the changes in the retinal vasculature in different parts of the fundus in eyes with primary angle closure glaucoma (PACG).

methodsHealthy subjects and those with PACG were enrolled. Optical coherence tomography and a split-spectrum amplitude decorrelation angiography algorithm were used to quantify the retinal vessel densities in the parafoveal and peripapillary areas.

resultsThirty-nine eyes from 24 PACG patients and 39 eyes from 20 age-matched and sex-matched healthy subjects were included. The retinal vessel densities in the parafoveal and peripapillary areas and every sector of the 2 areas were significantly lower in the PACG eyes than in the healthy eyes. The difference was greater in the peripapillary area (11.75%) than in the parafoveal area (7.55%, P<0.05). In the PACG eyes, the vessel density in the peripapillary area correlated closely with the intraocular pressure, but that in the parafoveal area did not. When the PACG eyes were divided into groups with well-controlled and not well-controlled intraocular pressure (≤21 mm Hg or not), the vessel density and retinal nerve fiber layer thickness in the peripapillary area were much lower in the not well-controlled eyes (P<0.05), whereas the vessel density in the parafovea and the ganglion cell complex thickness were similar in the 2 subgroups.

conclusionRetinal vessel density was significantly reduced in PACG eyes. The magnitude of this difference varied between the fundus areas, and was greater in the peripapillary area.
