Values in the table represent N (%) for categorical variables and mean (SD) otherwise; P for unadjusted differences are from Pearson’s chi-squared tests for categorical variables and t-tests for continuous variables.
SEP, socioeconomic position; LVH, left ventricular hypertrophy; PAD, peripheral arterial disease; CAC, coronary artery calcification; CIMT, carotid intima media thickness; SD, standard deviation; BMI, body mass index.
