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 aimed to explore the possibility of the clinical application using anterior segment optical coherence tomography angiography (AS-OCTA)-guided laser peripheral iridotomy (LPI). Methods: AS-OCT/OCTA was performed before LPI and at 1 hour, 1 day, and 1 week post-LPI. All the right eyes of patients with primary angle-closure suspect (PACS) were assigned to the AS-OCTA-guided group, in which the peripheral site with the sparsest iris vasculature on AS-OCTA images was selected for LPI. The left eyes underwent LPI in the slit lamp-guided group, where the site was chosen based on the presence of an iris crypt by clinicians using the slit lamp. The two groups were compared for the incidence of anterior chamber bleeding observed by the LPI operator, anterior chamber particle (ACP) index, mean angle opening distance (AOD750), and anterior chamber depth (ACD) measured from AS-OCT images, as well as the vessel density and perfusion area obtained from AS-OCTA images. Results: A total of 30 patients with PACS were included in this study. The incidence of anterior chamber bleeding during LPI was 13.33% in the AS-OCTA-guided group, compared with 43.33% in the slit lamp-guided group (P = 0.010). The prominent difference was observed 1 hour after LPI, with the AS-OCTA-guided group showing significantly lower vessel density (P = 0.028), perfusion area (P = 0.003), and ACP (P = 0.004), but a larger AOD750 (P < 0.001) compared with the slit lamp-guided group. Conclusions: Utilizing AS-OCTA to guide the LPI procedure can significantly decrease the incidence of anterior chamber bleeding and mitigate inflammation. Translational Relevance: This study shows that the AS-OCTA-guided LPI procedure could bridge advanced imaging technology and clinical glaucoma management.
