Facets of conscientiousness and motoric cognitive risk syndrome.
Article in Journal of psychiatric research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Conscientiousness is related to a lower risk of motoric cognitive risk syndrome (MCR), a pre-dementia syndrome characterized by slow gait speed and cognitive complaints. The present study examines which facets of conscientiousness are related to concurrent and incident MCR. Participants were dementia-free older adults aged 65-99 years (N = 6001) from the Health and Retirement Study (HRS). Baseline data on conscientiousness facets and MCR (cognitive complaints and gait speed) were collected in 2008/2010, along with the covariates: demographic factors, cognition, physical activity, disease burden, depressive symptoms, and body mass index (BMI). MCR was assessed again in 2012/2014 and 2016/2018. Controlling for demographic factors, higher industriousness was related to a nearly 30% lower likelihood of concurrent MCR (Odds Ratio [OR] = 0.75, 95%CI: 0.67-0.85, p < .001) and to about 60% reduced risk of incident MCR (Hazard ratio [HR] = 0.63, 95%CI: 0.56-0.71, p < .001). Self-control, order, and responsibility were also associated with a lower likelihood of concurrent (OR range: 0.82-0.88) and incident (HR range: 0.72-0.82) MCR. Traditionalism (HR = 0.84, 95%CI: 0.75-0.93, p < .01) and virtue (HR = 0.84, 95%CI: 0.75-0.93, p < .01) were related to a lower risk of incident MCR. Cognition, physical activity, disease burden, depressive symptoms, and BMI partially accounted for these associations. Industriousness is the facet of conscientiousness with the strongest association with risk of MCR. This facet could be targeted in interventions to reduce MCR and, ultimately, dementia.
