Retinal Vascular Density Change in Patients With Aortic Valve Regurgitation.
Article in Cardiology research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: The aim of this study was to assess retinal vessel density in the superficial capillary plexus layer, deep capillary plexus layer and choriocapillaris plexus layer in patients with aortic valve regurgitation (AR) using optical coherence tomography angiography (OCTA). Methods: Thirty-eight healthy participants (group 1) and 38 patients with AR (group 2) were assessed for this study. Diagnosis of AR is made by transthoracic echocardiography (TTE). Severity of AR was assessed according to values in the 2014 American Heart Association/American College of Cardiology (AHA/ACC) valve guideline. Superficial capillary plexus density (SCPD), deep capillary plexus density (DCPD) and choriocapillaris plexus density (CCPD) were analyzed between groups using OCTA. Results: SCPD measurements were found to be decreased in the nasal, inferior and central regions of patients with AR (P ≤ 0.05). DCPD measurements were found to be decreased in the nasal and inferior regions of patients with AR (P ≤ 0.05). CCPD measurements were found to be decreased in the inferior and central regions of patients with AR (P ≤ 0.05). In patients with AR, CCPD measurements were significantly decreased in the inferior region compared to the control group. Central macular thickness was found to be significantly decreased in the patients with AR. Conclusions: Patients with AR showed decreased flow density compared with healthy controls. Retinal perfusion measured using OCTA in patients with AR may give an idea about microperfusion.
