Relative frequency of BCVI correlated with the number of risk factors. The x-axis shows the number of risk factors characterising each patient group, whereas the y-axis reports the probability (in percentage) of having a BCVI for each group. The area of the blue circles is correlated with the size of each patient group (729 patients with no risk factors, 195 patients with one risk factor, 41 with two risk factors, 10 with three risk factors, 1 with four risk factors)
