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 evaluate the clinical efficacy and safety of posterior scleral contraction (PSC) in the treatment of myopic traction maculopathy (MTM) by three-dimensional magnetic resonance imaging (3D MRI), swept-source optical coherence tomography (SS-OCT) and swept-source optical coherence tomography angiography (SS-OCTA). Methods: In this prospective study, 30 eyes of 25 patients with MTM were treated with PSC. The ocular parameters of the patients were measured before surgery and at 1 month, 6 months, and 1 year after 3D MRI and SS-OCT/OCTA. Results: The differences in preoperative and postoperative parameters, including axial length (AL), spherical equivalent (SE), best-corrected visual acuity (BCVA), retinoschisis area, total posterior staphyloma height (PSH), and vitreous volume were statistically significant (P < 0.001). The choroidal thickness (CT) in each sector, choroidal perfusion area (CPA) in subfoveal and temporal sectors, and choroidal vascularity index (CVI) in inferior and temporal sectors increased significantly after PSC surgery (P < 0.05). Additionally, 3D MRI showed that the surgical strips remained strong and stable during the follow-up period, without complications such as strip displacement, fracture, and loosening. Conclusions: The application of 3D MRI and SS-OCT/OCTA in assessment of the treatment of MTM with PSC was comprehensive with multiple ocular parameters and could further guide the clinical diagnosis and treatment of MTM. Translational Relevance: We combined SS-OCT/OCTA and 3D MRI to provide the basis of a theory for guiding the clinical diagnosis and treatment of MTM.
