First and most important, for symptomatic stenosis patients, the number needed to treat to benefit within two years is between 3 to 19, depending on degree of stenosis and age. 15 For asymptomatic stenosis, as the Kaplan Mayer-curve suggests, at least five years of follow-up are needed to recoup the lost life years by increased morbidity and mortality (see further).
