c. Categorizing Recommendations without an Updated Review of the Evidence There were also cases in which it was necessary to carry forward recommendations from the previous version of the CPG without an updated systematic evidence review. Because of time and budget constraints, the update of the Dyslipidemia CPG could not review all available evidence on the management of dyslipidemia but instead focused its KQs on areas of new or updated scientific research or areas not previously covered in the CPG. For areas of research that have not changed and for which recommendations made in the previous version of the guideline were still relevant, recommendations could have been carried forward to the updated guideline without an updated systematic review of the evidence. The support for these recommendations in the updated CPG was thus also carried forward from the 2014 VA/DoD Dyslipidemia CPG. These recommendations were categorized as Not reviewed. If evidence had not been reviewed, recommendations could have been categorized as Not changed, Amended, or Deleted. Not reviewed, Not changed recommendations refer to recommendations from the previous version of the Dyslipidemia CPG that were carried forward unchanged to the updated version. The category of Not reviewed, Amended was used to designate recommendations that were modified from the 2014 VA/DoD Dyslipidemia CPG. Recommendations could also have been categorized as Not reviewed, Deleted if they were determined to be out of scope. A recommendation was out of scope if it pertained to a topic (e.g., population, care setting, treatment, and condition) outside of the scope for the updated CPG as defined by the Work Group. The categories for the recommendations included in the 2020 version of the guideline are noted in the Recommendations.
