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
objectivesThis study introduces the 3E framework of volunteering, including time exposure (e.g., volunteering hours), role engagement, and task essence (e.g., types of activities) and investigates how these dimensions and their interactions impact healthy aging outcomes in older adults.
methodsA mixed-methods cross-sectional study using purposive sampling was conducted in social care units with 457 participants aged 60 and older who volunteered at least one hour in the past year in Hong Kong (2024-2025), in addition to seven focus groups involving 46 older adults. Role engagement in volunteering was assessed using the adapted Chinese version of the Utrecht Work Engagement Scale.
resultsRole engagement (β = 0.92, p < .001), emotional support tasks (β = 1.35, p = .022), and creative activities (β = 1.09, p = .018) were positively associated with subjective well-being (SWB). Creative activities were linked to better self-rated health, while time exposure was associated with improved cognition. Role engagement amplified the health benefits of both time exposure and task nature. A three-way interaction among role engagement, time exposure, and creative tasks was significantly associated with better SWB (β = 0.66, p = .026) and lower depressive symptoms (β = -0.39, p = .027). Qualitative findings revealed that role engagement in late-life volunteering unfolds through four themes: role internalization, mental resilience, cognitive investment, and meaning-making. DISCUSSION: This study validates the 3E framework, demonstrating that role engagement optimizes the health benefits of late-life volunteering hours and volunteering types. Policymakers should transition from focusing solely on volunteering quantity to adopting a holistic approach that optimizes healthy-aging benefits of late-life volunteering.
