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: Although digital exclusion has been widely discussed in relation to healthcare access and digital service use, less is known about its implications for exercise participation among middle-aged and older adults. This study examined how individual digital literacy and area-level digital exclusion jointly shape exercise participation in China. Methods: Data were drawn from three waves of the China Health and Retirement Longitudinal Study (CHARLS; 2013, 2015, and 2018) and linked to city-year indicators from the China Statistical Yearbook. The analytic sample included 13,085 person-wave observations from 9,201 unique respondents across 111 cities. Exercise participation was measured as a binary indicator of engagement in exercise-oriented physical activity. Individual digital literacy was assessed using a composite index of digital access, internet use, device resources, and digital behaviors. Area-level digital exclusion was measured using a reverse-coded city-year indicator of contextual digital exclusion. Mixed-effects logistic regression models were used to estimate the associations of individual digital literacy and area-level digital exclusion with exercise participation and to test their cross-level interaction. Results: 37.7% of observations reported exercise participation, increasing from 27.5% in 2013 to 40.3% in 2018. In fully adjusted models, higher individual digital literacy was associated with greater odds of exercise participation (OR = 1.11, 95% CI: 1.022-1.208, Conclusion: Individual digital literacy was positively associated with exercise participation among middle-aged and older adults in China, whereas area-level digital exclusion weakened this beneficial association. Policies promoting healthy aging should address both older adults' digital literacy and the broader digital exclusion in which they live.
