All continuous data are presented as mean ± SD except alcohol and VC, which are median ± interquartile range. CKD, chronic kidney disease; eGFR, estimated GFR (modification of diet in renal disease 4-variable); AIx, augmentation index; PWVcr, carotid-radial pulse wave velocity; PWVcf, carotid-femoral pulse wave velocity; SFA VC, superficial femoral artery vascular calcification.
