Description of intervention(s) / exposure
Chronic Kidney Disease level of uremic toxins (serum analysis), CVD biomarkers (arterial stiffness by aortic pulse-wave velocity (PWV); atheroma burden by carotid intima-media thickness (cIMT) and endothelial function by flow-mediated dilation (FMD) of the brachial artery), and inflammation (serum markers) for two years.

All of the above will be performed at three time points baselines, 1 year and 2 year.
