Racial and ethnic differences in the associations of sensory impairments with cognition in older United States adults.

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
BackgroundSensory impairments are associated with cognitive decline and Alzheimer's disease risk.ObjectiveWe studied how sensory function and cognitive change varied by race/ethnicity in Hispanic, non-Hispanic Black (NHB), and non-Hispanic White (NHW) older US adults.MethodsWe studied 2799 individuals, 57-85 years-old, in the National Social Life, Health, and Aging Project with baseline sensory and follow-up Montreal Cognitive Assessment (MoCA) information from 2005-2016. Hearing was interviewer-rated; vision, smell, taste, and touch were objectively measured. Senses were categorized (poor, moderate, normal); number of poor senses (impairment) was summed. Multivariable linear regressions evaluated the association between sensory impairments and cognition, adjusting for demographic and clinical variables. We tested for differences by race/ethnicity using interaction terms.ResultsHispanic (n = 180) and NHB (n = 509) older adults had higher prevalence of ≥1 sensory impairments and lower cognition scores versus NHW respondents (n = 2110). Having multiple impairments significantly interacted with race/ethnicity such that estimates for the association with cognition was significantly lower for NHB versus NHW respondents (beta = -3.08, 95% CI: -5.14, -1.02; p = 0.004). Interactions were borderline significant for smell, where estimated difference in cognition associated with moderate (β=-0.91, 95% CI: -1.91, 0.10, p = 0.077) and poor (β=-1.33, 95% CI: -2.77, 0.11, p = 0.071) smell was lower for NHB versus NHW participants.ConclusionsOur findings suggest racial/ethnic differences in how strongly sensory impairments predict cognition, especially for number of impairments and possibly smell. Further insight may reduce disparities in cognitive aging.
