1 · What the graph read from it

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.

2 · The registry

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

Introduction: This longitudinal study investigated how social identity predicts civic engagement and vitality over time among Italian secondary school students participating in school-based outdoor nature education activities. Methods: A total of 203 students participated in a six-wave longitudinal study conducted over one academic year (control group, Results: Participation in the outdoor nature education program was associated with higher early levels of social identity and civic engagement compared with the control condition. Social identity significantly predicted civic engagement across multiple measurement waves, which in turn positively predicted vitality. A significant indirect effect of the intervention on vitality through social identity and civic engagement emerged during the initial intervention phase, whereas other indirect effects across subsequent waves were not statistically significant. The variability of effects over time may reflect developmental and contextual factors, including differences in program content and intensity across schools. Discussion: The findings support the role of social identity as a psychological foundation for civic engagement and suggest that school-based outdoor nature education may contribute to adolescents' psychological vitality by providing opportunities for belonging and meaningful collective participation. At the same time, variability across measurement waves and intervention contexts highlights the importance of considering program heterogeneity when evaluating the longitudinal effects of outdoor education initiatives.
