Association between visual impairment and sleep quality: A cross-sectional, comparative study of severity, eye conditions, and risk factors.

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/
objectivesVisual impairment (VI) is associated with significant disruptions in sleep quality. This study aimed to investigate the association between VI and sleep quality across varying severities of VI and ocular conditions in adults. SUBJECTS/
methodsA cross-sectional, observational, study was conducted among 277 adults with VI and 278 age- and sex-matched controls from two hospitals. Participants underwent comprehensive ocular examinations and completed the Arabic version of the Pittsburgh Sleep Quality Index (PSQI). Sociodemographic and clinical data were collected, and ocular conditions were recorded. Multivariate logistic regression models were used to evaluate the association between VI, its severity, ocular conditions, and poor sleep quality while adjusting for potential confounders.
resultsVI patients had worse sleep quality than controls (mean PSQI: 6.83 ± 3.6 vs. 5.30 ± 3.5; p < 0.001), with 57.8% experiencing poor sleep (PSQI > 5) compared to 36.7% of controls(p < 0.001). In multivariate analysis, patients with VI had significantly higher odds of poor sleep quality compared to controls (OR = 2.0 (95% CI: 1.4-2.8); p < 0.001). Moderate VI (OR = 2.1, 95% CI: 1.4-3.2, p = 0.001) and blindness (OR = 2.9, 95% CI: 1.4-5.9, p = 0.004) were significantly associated with poor sleep quality. Diabetic retinopathy (OR = 2.2, 95% CI: 1.4-3.4; p < 0.001) and combined ocular conditions (OR = 3.6, 95% CI: 1.4-9.3; p = 0.009) were significantly associated with poor sleep quality.
conclusionsVI is significantly associated with poor sleep quality, particularly in moderate VI and blindness. Diabetic retinopathy and combined ocular conditions were associated with poor sleep quality. Comprehensive management strategies addressing sleep in VI patients are essential for improving their overall well-being.
