Theory of change for building stronger wildlife health surveillance systems globally.
Review in The Lancet. Planetary health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Emerging and re-emerging infectious diseases affecting wildlife have highlighted the need for wildlife health surveillance (WHS), given the interconnected role of wildlife in maintaining the health of natural resources, agriculture, and human populations. Although global policies and guidelines exist, a key gap remains in the implementation of WHS systems at local and national levels. A working group of local, national, and global stakeholders in WHS was established to address this gap. In this Viewpoint, we report a theory of change (ToC) developed to support implementation of WHS from local to global scales. Using established methods for developing a collaborative ToC, we leveraged our expertise and identified six transformative pathways to be implemented via collaborations across scales and contexts: mindset change, policy and investment, evidence-based practice, user-driven technologies, capacity enhancement, and mobilisation of a global community of practice. This ToC serves as a roadmap for the development of effective WHS systems that support adaptive management and implementation. WHS is fundamental to understanding the impact of health threats on biodiversity, domestic animals, and humans. This ToC also presents an approach to operationalise the integration of wildlife health into collaborative One Health surveillance systems.
