An amended protocol may, at the discretion of the CRG, be published as a new citation version using the criteria in Box 3.2.b. This changes the formal citation of the document within CDSR, although citations for protocols are not included in MEDLINE or SCI.
New citation versions of protocols are further classified as having a major change or not. A protocol with a major change will be highlighted on CDSR.
