A modified measuring method to investigate the choriocapillaris flow void of polypoidal choroidal vasculopathy with swept source optical coherence tomography angiography.
Article in Quantitative imaging in medicine and surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
backgroundTo propose a modified method to investigate the flow void of polypoidal choroidal vasculopathy (PCV) choriocapillaris.
methodsThis paper involves a retrospective study. Included 30 PCV affect eyes, 30 old control eyes, 20 young control eyes, 15 affect eyes with anti-VEGF intravitreal injection treatment, and 8 fellow eyes of anti-VEGF intravitreal injection treatment group. After the choriocapillaris slab [10 µm thick starting 30 µm beneath to the retinal pigment epithelium (RPE)-fit reference] was extracted from macular optical coherence tomography angiography 6×6-mm scans, the flow void was segmented by the Phansalkar method. We analyzed the flow void sizes-frequency histogram in order to investigate the differences of flow void proportion between groups. Then we verified the differences between groups after anti-VEGF intravitreal injection treatment.
resultsOn the difference curve between the PCV group and Old control group, there was a peak appeared at the flow void sizes range from 900 to 1,125 µm
conclusionsOur method was specific for the pathological changes in choriocapillaris structures of PCV affect eyes, fellow eyes, and the affect eyes after anti-VEGF treatment.
