Seroprevalence of avian metapneumovirus (aMPV) among pullet and layer hens in Northern Thailand.
Article in Tropical animal health and production, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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) poses a significant global threat to the respiratory and reproductive systems of poultry, yet its prevalence and impact in specific regions, such as northern Thailand, remain understudied. This study is the first comprehensive assessment of aMPV seroprevalence among layer hens in the region. By the application of Enzyme-Linked Immunosorbent Assay (ELISA), our findings reveal a high overall seroprevalence of 60.78%, with significantly higher rates among post-laying hens (70.87%) compared to pre-laying hens (47.02%). Regional variations were noted, Uttaradit province showing the highest seroprevalence at 74%. Factors such as overcrowded conditions and poor farm hygiene were implied as contributors to increased seropositivity. Comparison with global studies highlights aMPV's endemicity and emphasizes the need for targeted surveillance and biosecurity measures. Migratory birds were inferred as potential vectors, contributing to the spread of aMPV across different regions. This study provides crucial epidemiological data essential for optimizing vaccination strategies and enhancing disease management practices to safeguard poultry health and sustainable production in northern Thailand.
