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
Purpose: This study aimed to expand the health belief model by incorporating dementia knowledge and fear and to assess the effects of these variables on dementia prevention behaviors among older adults. Methods: In total, 199 elderly individuals from 10 senior centers in Korea completed a structured questionnaire assessing characteristics, dementia knowledge, fear, health beliefs, and prevention behaviors. Measures included the Alzheimer's Disease Knowledge Scale, the Korean version of the Fear of Alzheimer's Disease Scale, and the Korean version of the Motivation to Change Lifestyle and Health Behavior for Dementia. Hierarchical polynomial regression was conducted to examine the impact of integrating dementia knowledge and fear into the health belief model. Results: Hierarchical polynomial regression across four models revealed significant effects of various factors on dementia prevention behaviors, explaining 12%-36% of the variance. Perceived barriers significantly decreased dementia prevention behaviors, while higher levels of self-efficacy and cues to action had a positive influence. Additionally, a nonlinear relationship was identified between dementia knowledge and prevention behaviors, with the positive impacts of increased knowledge potentially diminishing beyond a certain point. Conclusion: Our findings underscore the necessity of modifying the health belief model to integrate dementia knowledge and fear, which play critical roles in shaping preventive behaviors among older adults. Future investigations should examine the optimal level of dementia knowledge to promote these behaviors and elucidate the intricate relationship between knowledge and actions.
