  • Data are mean±SD or n (%). BP measured in the seated position; eGFR measured by the Modification of Diet in Renal Disease study equation for the CKD group and by the CKD Epidemiology Collaboration equation for the control group. BMI, body mass index; ACEi, angiotensin-converting enzyme inhibitor; ARB, angiotensin receptor blocker.

  • a P<0.05 by chi-squared or Fisher exact tests for categoric data and independent sample t test for continuous variables.
