Our study's conclusions were based on a composite of common, bulb, and internal carotid IMT measurements, whereas the ARYA study reported common carotid IMT measurements only (1). Furthermore, the mean and standard deviation carotid IMT values in our study were higher than in ARYA; therefore, cross-study reproducibility comparisons are not reliable. Nevertheless, carotid IMT reproducibility in our study was similar to many recent studies, and measurement precision in the ...References1. Oren A, Vos LE, Uiterwaal CS, Grobbee DE, Bots ML.
