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 observe the clinical features and serial changes of Acanthamoeba keratitis (AK) during medical treatment by using confocal microscopy.

methodsThirty-seven patients (37 eyes) diagnosed with AK were included in this study. Confocal microscopy was used to observe the morphology, distribution, and density of Acanthamoeba cysts before and after medication. The differences between cysts and inflammatory cells were identified.

resultsAcanthamoeba cysts were detected at a rate of 94.6% (35/37) by repeated confocal microscopic examinations. The cysts consisting of a lowly light-reflective wall and a high-refractive nucleus, showed cluster or chain distribution in the corneal stroma, which was different from inflammatory cells. After medical therapy, the nucleus of cysts or peripheral corneal tissue gradually dissolved to a hollow configuration. Some of the hollow cysts existed for up to 6 months. The quantity of cysts increased after 1-2 weeks of medication in 23 patients (62.1%), and then began to decrease in 13 patients (35.1 %) who were responsive to anti-amoebic treatment.

conclusionAcanthamoeba cysts have many typical clinical features that can be identified by confocal microscopy, which may serve as a valuable tool to guide clinical evaluation and treatment of AK.
