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 assess the choroidal vasculature with a novel three-dimensional (3D) algorithm in patients with central serous chorioretinopathy (CSCR).

methodsPatients with chronic CSCR were retrospectively included. Swept-source optical coherence tomography 12 × 12 mm scans were obtained. Automated choroidal segmentation was performed based on deep-learning ResUNet model. Phansalkar thresholding was adopted to binarize choroidal vasculature. Choroidal vessels were visualized in 3D maps segmented into 5 quadrants. Mean choroidal vessel diameter (MChVD), inter-vessel distance (IVD), choroidal thickness (ChT) and choroidal vascularity index (CVI) were calculated in CSCR and healthy eyes. Linear mixed models were used for analysis.

resultsThirty eyes of 25 CSCR patients and 30 eyes of 26 controls were included. Mean age of CSCR group was 51.2 ± 11.4 years, 24% were females. CSCR eyes showed significant increase in ChT and MChVD compared to controls in each sector (p < 0,001), with reduced IVD (p < 0.001). MChVD was increased in complex CSCR compared to simple CSCR in each sector, with significant differences in the nasal (p = 0.021), and temporal sectors (p = 0.020). CVI was reduced in complex CSCR compared to simple CSCR in each sector, with significant differences in the temporal (p = 0.017) and inferior sectors (p = 0.003). IVD in the central sector was reduced in active CSCR compared to inactive CSCR (p = 0.031).

conclusionsCSCR eyes demonstrated increased ChT and MChVD and decreased IVD compared to controls. Also, complex CSCR presented increased MChVD, along with reduced CVI compared to simple CSCR. Choroidal 3D vessel assessment represents an innovative non-invasive method to explore choroidal changes in CSCR.
