Neuropsychiatric symptoms and specific cognitive domains in mild cognitive impairment.
Article in Dementia & neuropsychologia, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Neuropsychiatric symptoms (NPS) such as depression, anxiety, and apathy are present in mild cognitive impairment (MCI) and are risk factors for cognitive decline. However, the relationship between NPS and specific cognitive domains is less clear. Objective: This study aimed to assess whether there is a correlation between NPS and specific cognitive domains. Methods: A cross-sectional study which included 174 participants with MCI, aged 55 years or older. Differences in sociodemographic profile, neuroimaging, and neuropsychological tests between MCI participants with and without NPS were measured. Results: Participants with NPS had lower education and worse performance in attention tests and executive functions. Psychotic symptoms were correlated with deficits in visuospatial functions; irritability and agitation with inattention and deficit of inhibitory control; and depression with inattention. Conclusion: Correlations were found between some NPS with specific cognitive domains, especially psychotic symptoms, but also agitation, irritability, apathy, and depression.
