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: This study employed swept-source optical coherence tomography angiography (SS-OCTA) to explore potential hemodynamic alterations in the retina and choroid following radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF). Methods: A total of 58 eyes from 32 patients were included, with SS-OCTA examinations conducted preoperatively and 1 day postoperatively. The evaluated parameters encompassed vessel density (VD) of the superficial vascular complex (SVC), VD of the deep vascular complex (DVC), choroidal vascular index (CVI), choroidal thickness (CT), thickness of the superficial retinal layer (SRL), and thickness of the deeper retinal layer (DRL). Results: Results indicated no significant changes in the VD of the SVC and DVC, nor in the thickness of the superficial and deeper retinal layers. Conversely, CT demonstrated a significant increase (P < 0.05) and the CVI exhibited a notable rise exclusively within the 1-mm diameter region centered on the fovea (P < 0.05). Conclusion: These findings underscore the remarkable hemodynamic stability of retinal microcirculation in the early postoperative phase. The observed increase in CT and localized elevation in CVI may signify compensatory mechanisms involving enhanced postoperative choroidal perfusion and redistribution of cardiac output, thereby reinforcing the choroid's superior sensitivity as a biomarker for detecting subtle hemodynamic shifts in AF-related ocular pathology.
