, Strong versus Weak ) should not be confused with the clinical importance of the recommendation. A Weak recommendation may still be important to the clinical care of a patient with HTN. 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 the 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 not offering this option ) Strong against (or We recommend against offering this option ) The grade of each recommendation made in the 2020 VA/DoD HTN CPG can be found in the section on Recommendations. Additional information regarding the use of the GRADE system can be found in 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.[19] For example, the U.S. Preventive Services Task Force (USPSTF) has a process for refining or otherwise updating its recommendations pertaining to preventive services.[20] The HTN CPG Work Group largely focused on developing new and updated recommendations based on the evidence review conducted for the priority areas addressed by the KQs.
