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 develop and validate a deep learning (DL) model for the automatic segmentation of lens opacity projected shadow (LOPS) on ultra-widefield (UWF) fundus images and to predict visual outcomes in children with congenital posterior lens opacities (CPLOs). Design: A prospective single-center study. Participants: Children with CPLO who underwent surgery at the Zhongshan Ophthalmic Center in China from January 2023 to November 2023. Methods: Demographics, best-corrected visual acuity (BCVA), biomicroscopic assessments, and UWF fundus images were collected. A DL model based on U-Net architecture was implemented for the segmentation of total and dense LOPS and optic disc. The ratio of LOPS to optic disc was defined as shadow-to-optic disc ratio (SODR). The DL model was evaluated by confusion matrix and Dice coefficients. An optimal visual outcome was defined as a BCVA better than 0.30 logarithm of the minimal angle of resolution. Factors correlated with optimal visual outcomes were identified by regression analyses, and predictive performance was evaluated by receiver operating characteristic curve. Main Outcome Measures: Pixel area of total and dense LOPS, total and dense SODR, and postoperative BCVA at a minimum 12-month follow-up. Results: Sixty eyes of 55 children with CPLO (mean age, 7.64 ± 3.73 years, 51.7% females) and 454 UWF fundus images were analyzed. The DL model achieved a sensitivity of 98.48% and a specificity of 91.62%, with Dice coefficients of 0.90, 0.83, and 0.84 for optic disc, total, and dense LOPS, respectively. Thirty-five eyes (58.3%) achieved optimal visual outcomes. A reduced dense-SODR was significantly correlated with optimal visual outcomes (odds ratio = 0.951, Conclusions: The LOPS on UWF fundus images can be accurately segmented by DL model. A dense-SODR ≤14.0 is associated with optimal visual outcomes, offering a novel, valuable predictor for visual outcomes in CPLO.
