A protocol provides a clear plan that outlines objectives, methods, and inclusion criteria before the review begins, helping to reduce bias and improve the reliability of findings. Registration in a publicly accessible database also promotes accountability, prevents duplication, and allows peers to evaluate the review’s methodology.

In fields like veterinary science and agriculture, where research directly shapes animal health, food systems, and policy, registering a protocol adds credibility and impact to a review, helping ensure decisions are well-informed and the discipline keeps moving forward.
