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
Climate change is increasingly recognized as a psychosocial and mental health challenge, yet the evidence remains fragmented across exposure types, populations, and outcome definitions. This umbrella review and meta-analysis synthesized evidence on the psychosocial impact of climate change and examined the usefulness of the Psychosocial Impact Model (PSIM) as an interpretive framework. Systematic searches were conducted in PubMed, Scopus, and Web of Science following PRISMA guidelines. Nine systematic reviews comprising 345 primary studies were included, and methodological quality was assessed with AMSTAR 2. Random-effects meta-analyses were conducted when sufficient quantitative data were available from high-quality reviews. Findings showed that climate change was associated with psychosocial variables across three exposure contexts: (1) acute, (2) chronic, and (3) symbolic. Outcomes included: psychological distress, depressive symptoms, posttraumatic stress, solastalgia, ecological grief, and climate anxiety, alongside adaptive responses such as resilience, posttraumatic growth, and community cohesion. Meta-analyses showed positive associations between climate-related anxiety or worry and mental health symptoms, with pooled correlations ranging from small to moderate magnitude ( Systematic Review Registration: https://osf.io/64rng, OSF.
