Sensitivity, specificity, and numbers needed to treat at 10 years for assigned LOE/class varied greatly among 5 CVD prevention guidelines. The level of variability seems to be driven by differences in how the evidence is graded and translated into LOE/class underlying the treatment recommendations by different professional societies. Efforts towards harmonizing evidence grading systems for clinical guidelines in primary prevention of CVD may reduce ambiguity and reinforce updated evidence-based recommendations.
