Association between self-reported sensory impairments and low cognitive performance in older adults: A cross-sectional study based on National Health and Nutrition Examination Survey (NHANES).

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: Early identification of risk factors is vital for the control of cognitive degenerative diseases, and sensory impairments could be potential candidate indicators. Objective: To determine whether self-reported hearing loss (HL), olfactory dysfunction (OD), and gustatory dysfunction (GD) are associated with low cognitive performance. Methods: Cross-sectional data from the 2011-2012 National Health and Nutrition Examination Survey (NHANES) were used. Data on participants' subjective hearing ability, olfactory and gustatory status were obtained from corresponding questionnaire datasets. Cognitive function was measured by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD), Animal Fluency Test (AFT), and Digit Symbol Substitution Test (DSST). The lowest quartile score of the four tests was used as the cutoff value to indicate low cognitive performance. Univariate and multivariate logistic regression analyses were conducted to investigate the association between sensory impairments and cognitive decline. Results: The data of 1416 adults aged ≥60 years were included. Univariate logistic regression analyses showed that the association between self-reported HL, OD, GD, and low cognitive performance was significant across all four cognition tests. Multiple models of multivariate logistic regression adjusted by covariate factors were established and showed significant association between self-reported HL, OD, GD, and low cognitive performance. Conclusions: Self-reported hearing loss, olfactory and gustatory dysfunction demonstrated significant associations with impaired cognitive performance in older adults. Multiple sensory impairments may lead to progressively worse cognitive performance.
