Understanding the impact of extreme weather events on non-communicable diseases in sub-Saharan Africa: a scoping review.
Article in BMJ public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Sub-Saharan Africa (sSA) is undergoing an epidemiological transition, with non-communicable chronic diseases (NCDs) rapidly becoming the leading cause of morbidity and mortality. Simultaneously, climate change is exacerbating the frequency, intensity and duration of extreme weather events, disproportionately affecting sSA. Extreme weather events strain healthcare, disrupting routine care for persons living with NCDs. The objective of this scoping review is to summarise the current evidence on the association of climate-related extreme weather events and NCDs in sSA. Methods: PubMed, Cochrane, Embase, PsycINFO (EBSCO), Web of Science, Global Health (CABI) and Scopus (Elsevier) were searched to identify peer-reviewed publications from 1995 to 2023, examining the effects of extreme weather events, including floods, droughts, cyclones, mud or landslides and extreme temperatures, on NCDs such as cardiovascular diseases, diabetes, respiratory conditions, cancer and mental health in sSA. Three reviewers conducted abstract screening of 903 articles, full-text screening of 108 articles and data extraction of 31 articles. Results: Of the 31 included articles, 27 reported on the mental health burden associated with floods and droughts. Few studies reported the impact of cyclones (4), extreme temperatures (3) and mud or landslides (2) on NCDs. Furthermore, we found a lack of geographic diversity among cited countries, with only 16 sSA countries represented in the literature. Conclusions: There is an urgent need for comprehensive research in under-represented sSA countries impacted by extreme weather events. Research needs to encompass a wider range of NCD outcomes, extreme weather events and countries. Lessons from other regions of the world can inform the development of cost-effective and climate-resilient strategies to reduce the impact of extreme weather events on NCD management in sSA.
