*P<0.05 was considered statistically significant. Values for continuous variables given as means±SD and test by student’s t-test, variables not normally distributed given as medians and interquartile range and test by Mann-Whitney U-test, Data are expressed as number of patients and analysis was done using the Chi-square test. ABI: Ankle brachial indices, HD: Hemodialysis, Kt/V: Fractional clearance index for urea, ACE: Angiotensin-converting enzyme, ARB: Angiotensin-receptor blocker, CCB: Calcium-channel blocker, SD: Standard deviation, BMI: Body mass index, SBP: Systolic blood pressure, iPTH: Intact parathyroid hormone, DM: Diabetes mellitus
