  1. cPTmax: maximal carotid plaque thickness. CACS: coronary artery calcium score. CV: cardiovascular. Number of valid cases = 170. Classical CV risk factors: age, sex, smoking (pack years), hypertension, hypercholesterolemia, and diabetes. a∆ p-values are derived from comparison with the base model that only controlled for time since baseline
