The Artifacts in Macular and Peripapillary OCT Angiography in Patients with Different Severities of Glaucoma.

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: To investigate the prevalence and types of artifacts in OCT angiography (OCTA) among patients with different glaucoma severities. Design: Prospective cross-sectional study. Subjects: Patients with open-angle glaucoma from a tertiary center were prospectively categorized into mild (mean deviation [MD] of 24-2 visual field ≥ -6 decibels [dB]), moderate (-6 to ≥ -12 dB), advanced (-12 to ≥ -20 dB), and severe glaucoma group (MD < -20 dB). Methods: AngioVue OCTA was performed three times within a single visit to obtain superficial and deep macular vessel density (VD) with 3 x 3-mm macular scans, and peripapillary VD with 4.5 x 4.5-mm scans centered on the optic disc. The intrasession variability was assessed by the coefficient of variation (CoV). Different types of image artifacts were identified. Main Outcome Measures: The prevalence of artifacts in patients with varying glaucoma severities, patient-related factors associated with artifact occurrence, and their impact on scan quality index (SQI) and variability of OCTA parameters. Results: Among the 57 mild, 46 moderate, 46 advanced, and 39 severe glaucoma eyes, half of OCTA images exhibited artifacts. Their prevalence increased from 30% in mild to 67% in severe glaucoma ( Conclusions: Defocus is the most common OCTA artifact in glaucoma patients, increasing variability in OCTA metrics. Its prevalence rises with glaucoma severity and remains high even in scans with acceptable image quality, emphasizing the need for careful artifact assessment.
