The validity of visual and hearing impairment in predicting dementia and cognitive impairment in older adults: a systematic review and meta-analysis.

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: The number of people with dementia and cognitive impairment is rising every year as the older population grows. The higher prevalence and mortality rates of dementia and cognitive impairment place an enormous burden on healthcare and economic systems worldwide. Studies have shown that older adults with sensory impairments are at a higher risk of developing dementia and cognitive impairment than normal older adults. There is a lack of systematic reviews on the relationship between sensory impairment and dementia and cognitive impairment in older persons. This meta-analysis aimed to analyze the correlation of visual impairment, hearing impairment, and dual sensory impairment with dementia and cognitive impairment, and to provide guidance for reducing the incidence of dementia and cognitive impairment in older adults. Methods: Computerized searches were conducted using the CNKI, Wanfang, Vip, Sinomed, PubMed, Web of Science, Cochrane Library, and Embase databases. Supplementary searches were performed on 2 clinical trial registries. Results: Meta-analysis was performed by log-transforming the study-specific estimates. The heterogeneity of studies was characterized by Q-test and Conclusion: Sensory impairment is a predictor of dementia and cognitive impairment. Healthcare professionals should prioritize screening older adults with sensory impairments to reduce the incidence of dementia and cognitive impairment.
