The longitudinal relation between purpose in life and accelerometer-measured physical activity.
Article in Mental health and physical activity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and Aims: Purpose in life is associated consistently with accelerometer-measured physical activity assessed concurrently. This research addresses the longitudinal relation between purpose and accelerometry-measured physical activity among older adults. Methods: Participants from the National Health and Aging Trends Study ( Results: Consistent with cross-sectional associations, purpose at baseline was associated prospectively with the four metrics measured one and two years later (median β=.08) but attenuated for two of the metrics at year three. Baseline purpose was associated with the intercept of physical activity but not change across the assessments. Within-person, participants were more physically active at assessments when their purpose was higher than their average. Conclusions: Purpose in life is a short-term prospective and within-person predictor of physical activity but is unrelated to the rate of change in accelerometer-measured physical activity over three years in older adulthood.
