Extreme weather events and pathways to mental health outcomes in sub-Saharan Africa: A systematic review.
Article in Climate risk management, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 has led to more frequent and intense extreme weather events (EWEs) globally, with sub-Saharan Africa (SSA) being disproportionately affected. Given the region's socioeconomic vulnerability and strong reliance on agriculture for subsistence, EWEs have the potential to affect the local population's mental health. The present systematic review synthesizes evidence on the impacts of EWEs on mental health in SSA, examining moderators and the pathways by which EWEs affect mental health, and identifying particularly vulnerable populations. In accordance with the PRISMA guidelines, we searched the PubMed, PsycINFO, and Web of Science databases and grey literature sources for relevant publications up to June 2024. Of the 3242 initially identified articles, 15 peer-reviewed journal articles from seven countries met the inclusion criteria. Studies examined floods (n = 8), droughts (n = 7), and heavy rainfall (n = 1) as EWEs, and reported psychological distress, anxiety, depression, and post-traumatic stress disorder (PTSD) as mental health outcomes. Findings indicate that EWEs affect mental health through both direct pathways, reflecting immediate psychological trauma from exposure, and indirect pathways, operating through displacement, economic instability, and water and food insecurity. Moderators included protective factors such as social support and religion, as well as risk factors such as being an adolescent, being female, and being economically disadvantaged. There were few longitudinal studies, a limited examination of heatwaves, and a lack of culturally sensitive strategies for mental health support, indicating evidence gaps. As the incidence of EWEs increases across SSA, there is an urgent need for expanded research, improved health systems, and targeted interventions for vulnerable populations.
