Analysis of factors influencing the efficacy of YAG laser vitreolysis for symptomatic vitreous opacities and prediction of postoperative complication risks: a retrospective cohort study.
Article in American journal of translational research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo identify factors influencing the efficacy of Yttrium Aluminum Garnet (YAG) laser vitreolysis for symptomatic vitreous opacities and to establish a risk prediction model for postoperative complications.
methodsThis retrospective study included 130 patients with symptomatic vitreous opacities who underwent YAG laser vitreolysis from January 2022 to December 2024. The relationships between patient demographics, clinical characteristics, surgical parameters, and treatment efficacy were analyzed. Multivariate logistic regression was applied to identify independent predictive factors for treatment efficacy. A risk prediction model for complications was constructed and evaluated using receiver operating characteristic (ROC) curve analysis.
resultsAt 3 months postoperatively, 78 (60.0%), 32 (24.6%), and 20 (15.4%) patients experienced marked, partial, and no improvement, respectively. Multivariate analysis identified age (OR=1.052, 95% CI: 1.012-1.093), disease duration (OR=1.105, 95% CI: 1.032-1.183), degree of vitreous opacity (OR=2.356, 95% CI: 1.325-4.187), and laser energy (OR=1.872, 95% CI: 1.235-2.841) as independent factors influencing efficacy (all P<0.05). Postoperative complications occurred in 70 (53.8%) patients. The prediction model demonstrated good performance, with an area under the curve (AUC) of 0.792, sensitivity of 0.714, and specificity of 0.667.
conclusionsThe efficacy of YAG laser vitreolysis is influenced by multiple factors. The established complication risk prediction model shows good predictive ability and may aid clinical decision-making.
