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: Primary angle-closure glaucoma (PACG) is a leading cause of irreversible blindness worldwide. However, the features of the morphology of Schlemm's canal (SC) in PACG eyes after phacoemulsification with goniosynechialysis (phaco-GSL) surgery are still unknown. This study aimed to evaluate changes in the SC in Chinese patients with PACG after phaco-GSL using swept-source optical coherence tomography (SS-OCT). Methods: In this prospective, cross-sectional study, 70 patients with PACG [of whom 35 had acute primary angle-closure glaucoma (APACG) and 35 had chronic primary angle-closure glaucoma (CPACG)] who were scheduled to undergo phaco-GSL surgery were recruited from the Eye, Ear, Nose, and Throat Hospital of Fudan University from December 2021 to December 2022. The anterior chamber angle (ACA), Schlemm's canal diameter (SCD), and Schlemm's canal area (SCA) were measured by SS-OCT at the baseline, and 1 month, 3 months and 6 months after surgery. A multivariate linear regression analysis was conducted to examine the predictors of change in the mean SCA and SCD. Results: Postoperative intraocular pressures (IOPs) were significantly reduced in both the APACG and CPACG patients (both P<0.01). The ACA, SCD, and SCA increased significantly after surgery, and this increase was maintained to the end of the follow-up period in both the APACG group (SCD: 104.62±8.70 Conclusions: SC expansion was observed after phaco-GSL surgery in patients with PACG (both APACG and CPACG). A correlation between SC expansion and the IOP decrease was also observed. Our findings suggest that SC provides valuable information that could be used to assess the efficacy of phaco-GSL.
