1 · What the graph read from it

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.

2 · The registry

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: Climate change has significant health implications, disproportionately affecting Africa because of its limited adaptive capacity and socio-environmental vulnerabilities. Malaria, a climate-sensitive disease, is a major public health concern. Climate change influences malaria transmission by altering vector behaviour, parasite life cycles and environmental conditions. Aim: To identify, map and analyse evidence on the relationship between malaria and climate change in Africa. Setting: The study examined institutional and community-based studies conducted in the African region. Method: A systematic review of studies published between January 2010 and December 2024 was conducted across PubMed, Scopus, African Index Medicus and Embase using keywords related to climate change and malaria. Thematic analysis was applied to synthesise patterns and trends. Results: Ninety studies were included. Findings demonstrate that slight temperature increases significantly impact malaria transmission by accelerating mosquito vector and parasite development. Changes in rainfall patterns, whether excessive or diminished, affect mosquito breeding sites, leading to fluctuations in malaria incidence. Regional variations highlight the need for localised interventions. Conclusion: Climate factors are crucial in malaria prevalence and distribution in Africa. As climate shifts alter mosquito populations, traditional interventions, such as chemical spraying, may become less effective. Integrating ecological data into malaria control strategies ensures interventions remain effective under changing climatic conditions. Strengthening climate-responsive policies will be pivotal in malaria reduction and elimination efforts. Contribution: This review offers a comprehensive synthesis of climate-malaria interactions, providing insights for policymakers and researchers to develop climate-informed malaria control strategies tailored to Africa's diverse ecosystems landscapes.
