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: Prosocial behavior, as an important social activity, plays a significant role in promoting the physical and mental health of older people. However, the existing measurement tools for prosocial behavior have primarily been developed for and applied to younger populations. There are no specific tools available to fully capture the nuances of prosocial behavior in older adults. Therefore, this study aimed to develop the Willingness of Prosocial Behavior Scale for community-dwelling older adults and to evaluate its psychometric properties. Patients and methods: Qualitative research, a two-round modified Delphi method, and cognitive interviews were utilized to build the scale items in stage 1, and the reliability and validity were tested using Classical Test Theory in stage 2. Community- dwelling older adults aged ≥ 60 years were selected to participate in interviews or face-to-face surveys. Results: The final scale included 14 items with four subdimensions: collectivity, relationship, tendency and altruism. The structural equation modeling (SEM) revealed a good model fit: χ Conclusion: The Willingness of Prosocial Behavior Scale exhibited good reliability and validity, and its development took into full account the collectivist cultural context, prosocial behavioral characteristics, and cognitive abilities of older adults. Future studies should focus on its application and additional testing by large-scale research with diversity types of older people.
