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: Northwest Nigeria is highly vulnerable to climate variability and heavily dependent on rain-fed agriculture, which exacerbates existing socioeconomic vulnerabilities. Aim: This study aimed to explore the link among climate-induced stress, poverty, and mental health outcomes, particularly substance use as a maladaptive coping mechanism, in this region. Setting: The study was conducted in Kano, Kaduna, and Katsina in Northwest Nigeria. Methods: A cross-sectional study was conducted among 20 000 adults aged ≥ 18 years from 40 randomly selected communities. Data were collected using validated instruments: The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), the Kessler Psychological Distress Scale (K10), the Coping Strategies Inventory-Short Form (CSI-SF), and a Multidimensional Poverty Index Questionnaire. Robust statistical analyses, including multivariable logistic regression with cluster-robust standard errors, were employed. Results: The prevalence of high-risk substance use (ASSIST ≥ 27) was 18.5% ( Conclusion: This study reveals a concerning syndemic of climate-related stress, profound poverty, poor mental health, and substance use in Northwest Nigeria. Associations suggest substance use may function as a maladaptive coping mechanism in the context of climate-induced economic hardship, though causal inference is limited by the cross-sectional design. Contribution: Findings underscore the critical need for integrated public health interventions that address mental health and substance use disorders within the context of climate adaptation and poverty reduction strategies.
