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: Climate change is increasingly recognized as a source of significant psychological distress. How can we best minimize its mental health impacts? This study examines community-grounded theories of change by modelling how cognitive, emotional, and social processes shape climate-related psychological distress and adaptation. Methods: This cross-sectional study surveyed Canadian adults, measuring climate change perceptions (reality, causes, consequences, and psychological distance), climate worry, psychological distress, climate change anxiety, resilience, social support, belonging, and pro-environmental behaviour. Structural equation modelling (SEM) was used to test three theoretically informed models: (1) a cascade from climate perceptions to distress via worry and impairment, (2) a social-ecological model of support, resilience, and belonging, and action and (3) a combined model integrating cognitive, emotional, and social pathways. Results: Of 840 participants, 665 completed the survey. The mean sample age was 45·3 years (SD = 18·17). 70·3% identified as women, 18·3% as men, and 11·4% as gender diverse. Model 1 and Model 2 showed excellent fit. Model 3, which had a strong fit, showed that greater climate change perceptions predicted higher climate worry (β = 0·46, p <0·001), which led to greater impairment (β = 0·91, p <0·001), which led to distress (β = 0·32, p <0·001). Greater climate change perceptions had a buffering effect on impairment (β = -0·21, p < 0·001) and predicted distress (β = 0·55, p < 0·001). Stronger social networks predicted increased belonging (β = 0·85, p <0·001) and resilience (β = 0·61, p <0·001), each of which buffered psychological distress (resilience: β = -0·29, p <0·001; belonging: β = -0·06, p = 0·028). Resilience was a buffer against climate change perceptions (β = -0·43, p <0·001) and climate change worry (β = -0·28, p <0·001). Pro-environmental action predicted stronger climate change perceptions and climate worry (perceptions: β = 0·38, p <0·001; worry: β = 0·33, p <0·001). Conclusion: These findings support the value of community-based and psychologically informed approaches for minimizing climate-related psychological distress. Interventions that prioritize social support and emotional skills, together with accurate climate communication, may be critical for fostering mental health and collective resilience in a changing climate.
