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
Introduction: Climate-related events such as droughts, extreme heat, and flooding intensify pressures on psychological well-being, particularly in vulnerable, low-resource, and conflict-affected settings. Iraq ranks as the world's fifth most climate-vulnerable country, and the Kurdistan Region has been increasingly affected by frequent and intense extreme weather events that threaten livelihoods and community stability. Despite rising exposure, the mental health impacts of climate change in the Kurdistan Region remain largely understudied. This study investigates the effects of climate change-related stressors and extreme weather events on mental health through robust analytical methods, yielding the first rigorous empirical evidence from the region. Methods: An analytical cross-sectional study was conducted with a sample of 618 participants aged ≥18 years, residing in urban and rural areas of three governorates in the Kurdistan Region of Iraq: Duhok, Erbil, and Sulaymaniyah. Data were collected using a questionnaire that integrated measures from several validated psychological scales, including the PHQ-8, GAD-7, K10, PCL-5, and CC-MMDS. The data were analyzed using independent t-tests and analysis of variance (ANOVA) for group comparisons, and multiple linear regression for associations. Results: The final sample included N = 608 adults aged 18-75 years (51.6% male, 48.4% female), recruited from Duhok (32.9%), Erbil (33.9%), and Sulaymaniyah (33.2%). Descriptive analysis identified heatwaves, droughts, and dust storms as the most frequently reported extreme weather events. Multiple linear regression analyses revealed that exposure to extreme weather events significantly predicted increased posttraumatic stress disorder symptom levels ( Conclusion: The study found that individuals in the Kurdistan Region of Iraq who were exposed to climate-related stressors, such as extreme weather events and climate-induced homelessness, presented significantly poorer mental health outcomes compared to those without such exposure. These findings underscore the severe psychological impact of environmental changes and highlight the urgent need for targeted support within climate adaptation and disaster response strategies, especially for populations that are most directly affected.
