Occasionally, instances may occur when the Work Group feels there is insufficient evidence to make a recommendation for or against a particular therapy or preventive measure. This can occur when there is an absence of studies on a particular topic that met evidence review inclusion criteria, studies included in the evidence review report conflicting results, or studies included in the evidence review report inconclusive results regarding the desirable and undesirable outcomes. Using these elements, the grade 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 ) Note that weak (For or Against) recommendations may also be termed Conditional, Discretionary, or Qualified. Recommendations may be conditional based upon patient values and preferences, the resources available, or the setting in which the intervention will be implemented. Recommendations may be at the discretion of the patient and clinician or they may be qualified with an explanation about the issues that would lead decisions to vary. E. Recommendation Categorization a. Recommendation Categories and Definitions A set of recommendation categories was adapted from those used by NICE.[8,9] These categories, along with their corresponding definitions, were used to account for the various ways in which recommendations could have been updated from the 2014 VA/DoD Dyslipidemia CPG. The categories and definitions can be found in Table A-5. Table A-5.
