Factors Influencing the Willingness of Layer Specialized Households to Participate in Cooperative Avian Influenza Prevention and Control: Evidence from China.
Article in Veterinary sciences, 2025. 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
backgroundHighly pathogenic avian influenza (HPAI) remains a significant threat to poultry production in China. Layer specialized households (LSHs)-characterized by medium-scale operations (1000-15,000 birds)-are particularly vulnerable due to frequently suboptimal biosecurity measures. Cooperative prevention and control (CPC) strategies, including unified disinfection and joint monitoring, present a viable method for reducing HPAI risks. However, participation among LSHs remains low.
objectivesThis study seeks to identify the key determinants influencing LSHs' willingness to participate in CPC measures against HPAI, and further compare these driving factors across villages with versus without a documented history of HPAI outbreaks.
methodsA survey of 130 LSHs was conducted in two Chinese villages: Village A (with HPAI history) and Village B (without HPAI history). Data on socio-economic characteristics, production practices, and attitudes were collected via structured questionnaires. An Ordered Probit model was employed to analyze determinants of willingness to participate, measured on a 5-point ordinal scale.
resultsFull-sample regression analysis demonstrated that older age, higher educational attainment, risk-tolerant attitudes, larger household scale, and higher annual household income exerted a significantly positive impact on the willingness to participate in the program. Surprisingly, greater knowledge of avian influenza exerted a significant negative effect. Regional subgroup analyses identified distinct drivers: in Village A (with HPAI history), prior experience of bird deaths positively influenced willingness, whereas longer breeding experience had a negative effect. In Village B (no HPAI history), frequent social interaction and greater breeding experience emerged as positive determinants.
conclusionsThe findings underscore the critical role of regional context and specific household characteristics in shaping LSHs' willingness to cooperate. Policy interventions to promote CPC should be regionally tailored: in previously affected areas, leveraging past outbreak experiences and ensuring equitable compensation is essential; in unaffected areas, fostering social networks and demonstrating CPC benefits through peer influence are more effective.
