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

Aerobiology is pivotal for understanding human health risks, ecosystem dynamics, as well as plant reproduction, including phylogeny. Africa's vast climatic and ecological diversity-from deserts to tropical rainforests-produces complex, region-specific aerobiological patterns that are often underinvestigated. Seasonal and meteorological factors, including rainfall, temperature, humidity, wind, and phenomena such as the Harmattan, significantly influence the distribution of airborne pollen and fungal spores, with direct implications for allergen exposure and the development of respiratory diseases. These complex systems are altered by anthropogenic climate change and disturbances. Despite these impacts, continent-wide aerobiological research remains limited, with most studies concentrated in research-strong nations such as South Africa and Nigeria. This review synthesizes current knowledge on African aerospora, highlighting spatial and temporal trends, dominant taxa, environmental drivers, sampling methodologies, and links to allergic disease, including projections under climate change. Data were collated from PubMed, Web of Science, Scopus, African Journals Online, and long-term monitoring initiatives. Key research gaps include sparse long-term monitoring data, inconsistent methodologies, and limited integration with public health outcomes and modelling approaches. Expanding monitoring networks and fostering interdisciplinary approaches are essential for improving our understanding of African aeroallergens and informing strategies to mitigate allergy and respiratory health risks, such as inhibiting the spread of invader plants such as
