[8,9] These categories and their corresponding definitions were used to account for the ways that older recommendations could have been updated. In short, the categories explain whether the evidence related to a recommendation was systematically reviewed, the degree to which the recommendation was modified, and the degree to which a recommendation is relevant in the current care environment and within the scope of the CPG. For additional information regarding these categories and their definitions, see Recommendation Categorization. The 2020 CPG recommendation categories can be found in the Recommendations section. Appendix G outlines the categories for the recommendations carried forward from the 2014 VA/DoD Dyslipidemia CPG. The Work Group recognized there may be practical reasons for incorporating findings from a previous systematic review (SR), previous recommendations,[10] or recent peer-reviewed publications into an updated CPG. However, because this would not involve an original, comprehensive systematic evidence review, it may introduce bias. c. Peer Review Process The CPG was developed through an iterative process (i.e., the Work Group produced multiple drafts). The process for developing the initial draft is detailed in Drafting and Submitting the Final Clinical Practice Guideline. Once the Champions and Work Group agreed upon a near-final draft of the guideline, the draft was posted for a 14-business-day peer review and comment period. The peer reviewers comprised individuals working within the VA and DoD healthcare systems and experts from relevant outside organizations designated by the Work Group members. VA and DoD Leadership contacted internal and external peer reviewers to solicit their feedback on the CPG. The Work Group considered all feedback from the peer reviewers. Modifications made throughout the CPG development process were made in accordance with the evidence. B.
