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: Cataract, a major health concern among the elderly, can be influenced by environmental exposures. This study examines the association between per- and polyfluoroalkyl substance (PFAS) exposure and cataract prevalence. Methods: Six serum PFAS concentrations were detected among 2119 U.S. adults aged 40 years or older based on the National Health and Nutrition Examination Survey. Multivariable models, including weighted logistic regression, weighted quantile sum (WQS) regression, and Bayesian kernel machine regression, were used to assess the association between individual and overall PFAS exposure and cataract prevalence. A mediation analysis was conducted for inflammation biomarkers. Results: Single exposure to perfluorohexane sulfonic acid (PFHS) and perfluorononanoic acid (PFNA) was found to be markedly associated with cataract prevalence after adjustment for covariates (PFHS: odds ratio [OR], 1.579; 95% CI, 1.003-2.514; PFNA: OR, 1.629; 95% CI, 1.065-2.506). The WQS index was significantly associated with cataract (OR, 1.441; 95% CI, 1.130-1.837). PFNA and PFHS were the most influential exposures in the PFAS mixture. In the Bayesian kernel machine regression model, PFNA and PFHS exhibited the highest group posterior inclusion probability, aligning with the WQS results. Moreover, serum albumin and neutrophil counts were found to mediate the relationship between PFHS and cataract, accounting for -26.20% and -5.95% of the mediation effect, respectively. Conclusions: Exposure to PFAS was positively associated with cataract, primarily driven by PFHS and PFNA. Mediation of serum albumin and neutrophil count was observed. Translational Relevance: This study links PFAS exposure to cataract prevalence, suggesting reducing exposure could help in cataract prevention.
