Abbreviations: DBP, diastolic blood pressure; GFR, glomerular filtration rate; MDRD, Modification of Diet in Renal Disease study group; SBP, systolic blood pressure. a T test/Chi‐square test/Fisher exact test was used to calculate the P value. bNumbers in parentheses are one standard deviation for continuous variables and 95% confidence interval for percentages. cPulse pressure = SBP – DBP. dMean arterial pressure=[(2*DBP) + SBP]/3.
