There was a significant trend toward an increase in the number of arterial lesions (r = 0.244, p < 0.001).
There was a significant trend toward an increase in the number of arterial lesions (r = 0.244, p < 0.001).
Likewise, the proportion of severe atherosclerosis showed a similar increasing trend ( p = 0.043), although it did not reach statistical significance in the analysis using the DSA findings ( p = 0.075).
However, an increasing trend of atherosclerosis was also observed in a subgroup using DSA, indicating that the findings and conclusions in our study were not impacted by the use of MRA data.
