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
Sedentary behavior poses significant risks to older adults yet remains an understudied health risk behavior. Studies typically overlook the importance of subject-level variability in psychological constructs as predictors of sedentary behavior, instead focusing on the role that typical or mean levels of these constructs play in predicting behavior. This study uses ecological momentary assessment and device-based sedentary behavior to determine the role of subject-level variability in psychological constructs as predictors of sedentary behavior in older adults. Findings reveal that subject-level variability in positive affect, but not motivational or self-regulatory constructs, is associated with sedentary behavior (total sedentary behavior: β = -18.136, SE = 8.284, p = .029; bouted sedentary behavior: β = -16.534, SE = 7.814, p = .034). The association between subject-level variability and total sedentary behavior tended to be positive but marginally significant among participants with lower mean levels of positive affect but was negative and significantly different from zero among participants with higher mean levels of positive affect. These findings highlight the importance of considering not only mean levels but also within-person fluctuations in psychological constructs as key predictors of sedentary behavior. Studies of this kind can inform the development of personalized interventions, tailored to patterns of determinants in key constructs.
