  1. Abbreviations: BP, blood pressure; CAD, coronary artery disease; CAVI, cardio-ankle vascular index; CRP, C-reactive protein; eGFR, estimated glomerular filtration rate; Hb, hemoglobin; HDL, high-density lipoprotein; LDL, low-density lipoprotein.
  2. Values are mean±s.d. or n (percentage). The column showed P-values for the comparison between patients with persistently impaired CAVI and those with improved CAVI.
