The use of hypertext (e.g. hyperlinks and URLS) in NIH applications is restricted due to concerns including reviewer confidentiality, “overstuffing” applications, review consistency, and malware. There is no change in the NIH policy on the use of hyperlinks.
It would be hard to read more than a couple paragraphs on the internet these days without encountering a hyperlink to a definition or additional clarifying information. Hyperlinks are everywhere. So, why does NIH limit the use of hyperlinks in grant applications?
