Results: The manual approach provided intra-operator CV of 6.6% and 3.9% for DD and 6.5% and 6.6% for IMT (first and second operator). The automatic approach provided CV equal to 6.6%, 5.4%, 4.5% and 3%, respectively. Inter-operator CV were 11.3% for DD and 3.9% for IMT (manual), and 10.9% and 5.8% (automatic). Bland-Altman analysis provided non-significant bias for both IMT and DD measurements comparing manual and automatic approach. In the whole population, radial IMT was correlated with age

No sex differences were observed. Conclusions: We obtained good CV values for both the intra-and inter-operator reproducibility; furthermore, the manual and the automatic approach provided similar results. Radial IMT increases with age and pulse pressure.
