Cross-sectional survey of sources of information accompanying veterinary product advertisements in two professional print publications.

Background: Veterinarians should be able to easily access scientific evidence about medical products and devices to incorporate into their clinical decision making. While the characteristics and quality of supporting information accompanying device and pharmaceutical advertisements have been studied in human medicine, little is known about this topic in veterinary medicine. The aim of this study was to characterise the supporting information provided by manufacturers of prescribed products, tests or devices in promotional material found in two commonly read UK-based veterinary publications.
