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 In recent years, research on caregivers has highlighted the importance of integrating advanced technologies, such as wearable devices. Furthermore, when investigating the characteristics of persons with dementia (PWD), comparative analyses should be conducted based on the presence or absence of the condition. We aimed to elucidate the relationship between caregivers' subjective burdens, tasks, and heart rate (HR) using wearable sensors to objectively assess the health status of caregivers of PWD and older adults requiring long-term care. Methods The study recruited 21 caregivers of PWDs and older adults requiring long-term care between September 2022 and December 2024 from one hospital, two care plan centers, and visiting nursing stations in Fukuoka Prefecture, Japan. We collected the participants' sociodemographic data using a questionnaire survey for caregivers. We also measured the caregiver's HR, walking steps, and total sleep time using a wearable sensor. Results Data from 17 participants with no missing values were included in this analysis among the 21 caregivers who provided consent to participate in this study. The demographic variables of the caregivers and care recipients revealed that the caregivers were predominantly female (typical spouses). Most PWDs were diagnosed with atopic disease. No significant correlations were found between the short Japanese version of the Zarit Burden Interview (J-ZBI_8) and the following measures: caregiving years, activities of daily living (ADL), the 14-item Short-Memory Questionnaire (SMQ), caregiving time, the Caregiving Gratification Scale (CGS), total caregiving tasks, sleep time, walking steps, or conversation time. Caregiver burden was significantly associated with caregiving experience and continued caregiving. We observed no significant differences in the average HR for pre- and post-caregiving tasks. Significant differences were found in the maximum pre- and post-caregiving HR. While caregiver burden showed a high-scoring trend and positive perception showed a low-scoring trend, none of the variables differed according to the presence or absence of PWDs. Conclusions These results indicate that subjective appraisal of caregiver burden was not significantly associated with HR change during caregiving tasks. No differences were observed in the behaviors of caregivers with or without dementia. It is necessary to measure subjective and objective appraisals using wearable sensors to better understand caregivers' situations.
