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
Understanding the role of trust in shaping pro-ecological behaviour is essential for advancing effective environmental communication, particularly in societies characterized by low institutional credibility. This study examines how different forms of trust-scientific, institutional, mediatic, and interpersonal-predict pro-ecological behaviour in Bulgaria, a context marked by historically low levels of social and institutional trust. Drawing on a nationally representative survey of 1008 adults, participants rated their trust in six sources of environmental information (experts, public servants, politicians, media, social networks, and friends or relatives) and reported their engagement in various ecological practices. Multiple regression analysis revealed that trust in experts was the strongest positive predictor of pro-ecological behaviour, followed by trust in friends and relatives. Trust in political institutions, media, and online social networks showed no significant associations. These findings suggest that in low-trust societies, interpersonal trust and trust in experts serve as primary drivers of ecological engagement, while institutional trust alone is insufficient to mobilize collective environmental action. The study underscores the importance of fostering both scientific credibility and community-based communication to enhance public participation in sustainability initiatives.
