Occasionally, there is insufficient evidence to make a recommendation for or against a particular therapy or preventive measure, such as when there is an absence of studies that met evidence review inclusion criteria, or when studies included in the evidence review report had conflicting or inconclusive results. Using these elements, the strength of each recommendation is presented as part of a continuum: Strong for (or We recommend offering this option ) Weak for (or We suggest offering this option ) No recommendation for or against (or There is insufficient evidence ) Weak against (or We suggest against offering this option ) Strong against (or We recommend against offering this option ) The strength of each recommendation can be found in the Recommendations section. For additional information regarding the use of GRADE, see Appendix A. b. Reconciling 2014 Clinical Practice Guideline Recommendations Evidence-based CPGs should be current, which typically requires revisions of previous guidelines based on new evidence, or as scheduled and subject to time-based expirations.[6] For example, the U.S. Preventive Services Task Force (USPSTF) has a process for refining or otherwise updating its recommendations pertaining to preventive services.[7] This Work Group developed new and updated recommendations based on the evidence yielded from this CPG s key questions. The Work Group also considered the current applicability of the recommendations included in the 2014 VA/DoD Dyslipidemia CPG that were not addressed by the KQs in light of evolving practice in today s environment. Accordingly, some of the 2014 VA/DoD Dyslipidemia CPG s recommendations do not appear in this updated CPG. Recommendation categories were adapted from those used by the National Institute for Health and Care Excellence (NICE).[8,9] These categories and their corresponding definitions were used to account for the ways that older recommendations could have been updated.
