FIGURE 1.

Change in JAK2 V617F mutation burden and Agatston coronary calcium score over the 4-year observation period in patients whose JAK2 V617F mutation burden increased (left-side columns) and in patients whose mutation burden decreased (right-side columns). Bar charts represent the mean mutation burden (%), and line graphs represent the median Agatston coronary calcium score.
