Associations between cataract and cognitive impairment in a sample of the United States Population.

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/
objectiveVisual impairment has recently been identified as a key modifiable risk factor for dementia. This study investigates the associations between cognitive impairment with both cataract diagnosis and sociodemographic determinants in a large representative sample of the United States civilian, noninstitutionalised population. SUBJECTS/
methodsThis is a Cross-sectional study using data from the 2023 iteration of the National Health Interview Survey (NHIS). Participants of the NHIS were included if they answered key questions regarding cognitive impairment and cataract. The primary outcomes included the associations between cognitive impairment with cataract, controlling for sociodemographic factors and modifiable risk factors for dementia. Associations were modelled through univariable and multivariable logistic regression analysis.
resultsOverall, 29,522 participants were included in the study, comprising 13,462 males (45.6%) and 16,060 females (54.4%). Of these, 19,781 (67.0%) were under the age of 65, while 9,741 (33.0%) were 65 or older. Univariable analysis showed that there were higher odds of cognitive impairment amongst those with cataract (OR = 2.31, p < 0.001). Multivariable analysis showed significant associations between cognitive impairment with cataract (OR = 1.58, p < 0.001), high cholesterol (OR = 1.49, p = 0.004), depression (OR = 2.75, p < 0.001), history of traumatic brain injury (OR = 1.52, p < 0.001), smoking (OR = 1.16, p < 0.025), social isolation (OR = 4.11, p < 0.001), low levels of physical activity (OR = 1.69, p < 0.001), and hearing impairment (OR = 2.26, p < 0.001).
conclusionsCognitive impairment was robustly associated with cataract in a representative sample of the United States civilian population age 18 and older. Health policymakers should consider the impact of cataract in designing preventative and treatment strategies for individuals with cognitive impairment.
