Association between trouble sleeping and cataract in US adults: a cross-sectional study.
Article in Frontiers in medicine, 2026. 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
Objective: To investigate the association between trouble sleeping and cataract in US adults, given the increasing global burden of cataracts and the high prevalence of sleep problems. Methods: This cross-sectional study analyzed data from 2,601 adults aged ≥40 years in the National Health and Nutrition Examination Survey (2005-2008). Trouble sleeping was assessed through self-reported diagnosis, and cataract status was determined by self-reported history of cataract operation. Multiple logistic regression models were adjusted for sociodemographic factors, lifestyle variables, and comorbidities. Results: Participants with trouble sleeping had significantly higher odds of cataracts (OR = 2.50, 95% CI: 1.35-4.62, Conclusion: Trouble sleeping was significantly associated with increased odds of cataracts in US adults. These findings suggest potential value in incorporating sleep health into cataract prevention strategies. Future longitudinal studies are needed to confirm causality, explore underlying mechanisms, and evaluate the impact of sleep interventions on cataract risk.
