Outcome Measures

Primary Outcomes (1)

  • the improvement of coronary artery calcification

    We use CT to detect the coronary artery calcification score in the chronic kidney disease patients for 3 times (baseline, 12 month and 24 month). We will compare the 2 arms (treatment or not)to know if there is any difference。
