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
Purpose: The study utilized wide-field swept-source optical coherence tomography angiography (SS-OCTA) to examine the alterations in retinal and choroidal blood flow in patients with end-stage renal disease (ESRD) before and after hemodialysis. Methods: Forty-two eyes of 24 participants with end-stage renal disease were enrolled in this prospective and cross-sectional study. A full ophthalmic examination was conducted on each participant 1 h before and after hemodialysis, which included wide-field SS-OCTA imaging on OCTA scans measuring 9 mm x 9 mm. The mean perfusion area (PA), superficial vessel density (SVD), retinal inner VD (RIVD), and choroidal vascularity index (CVI) were evaluated independently before and after hemodialysis in both macular and optic disk areas across all 16 sectors defined by the Early Treatment Diabetic Retinopathy Study (ETDRS). Results: The study subjects consisted of 18 men and 6 women, comprising 9 patients with diabetic renal failure and 23 patients with hypertension. The mean age of the patients with end-stage renal disease was 57.3 ± 12.7 years. In the central ring, retinal inner VD were significantly decreased after HD ( Conclusion: Results revealed a more significant decrease in indicators of the choroid and optic disk area compared to the inner retina and macular zone. Wide-field SS-OCTA displays potential as an imaging technique for early detection of microcirculation changes in hemodialysis patients.
