Book excerpt: The aim of this protocol is to support the conduct of entomological comparative efficacy assessments for vector control products and the associated non-inferiority analysis. This evidence is used to inform discussions within the guidelines development context as to whether a new vector control product should be considered as covered by one or more existing WHO recommendations or not. Alternatively, the evidence may inform the extension of an existing WHO recommendation or the development of a new one, provided that non-inferiority is demonstrated.
