New Indices of Endothelial Function Measured by Digital Thermal Monitoring of Vascular Reactivity: Data from 6084 Patients Registry

Figure 4

(a) Prevalence of poor VRI in different age groups. The frequency of having a poor VRI score (VRI < 1.0) is shown for the three age categories of age < 50 y, age 50–70 y, and age 70 y. (b) Distribution of vascular reactivity index (VRI) in oldest age group. The percent of tests falling into categories of poor, intermediate, and good vascular reactivity is shown for patients age 70 years.
