Avian Metapneumovirus: A Narrative Review of Biology, Epidemiology, Transmission Ecology, Diagnostics and Control with Special Reference to Africa and the Middle East.
Review in Veterinary sciences, 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
Avian metapneumovirus (aMPV) is an important respiratory pathogen of poultry associated with respiratory disease, reproductive losses, secondary bacterial complications, and economic losses in commercial poultry systems worldwide. This narrative review summarizes current evidence regarding the epidemiology, molecular diversity, transmission ecology, diagnosis, vaccination, and wildlife-poultry interactions of aMPV across Africa and the Middle East. This literature was identified through structured searches of PubMed, Scopus, Web of Science, Google Scholar, and ScienceDirect using predefined keywords related to epidemiology, molecular characterization, surveillance, wild birds, diagnostics, and vaccination. Available evidence demonstrates widespread endemic circulation of aMPV, with subtype B predominating across most investigated poultry systems. However, major heterogeneity exists among studies regarding surveillance intensity, diagnostic methodologies, molecular characterization, and reporting standards. Current evidence suggests possible involvement of wild birds in viral dissemination, although definitive reservoir competence and transmission directionality remain insufficiently established. Important surveillance gaps persist across several African and Middle Eastern countries, emphasizing the need for harmonized surveillance, subtype-matched vaccination strategies, and integrated regional monitoring.
