Abbreviations: ACEI: angiotensin converting enzyme inhibitor; ARB: angiotensin II receptor blocker; sUCr: spot urine creatinine concentration. To convert creatinine to μmol/L, multiplied by 88.4. aAs indicated, a comparison for the means among the various ethnic groups is performed using the one-way analysis of variance (ANOVA) along with the Bonferroni method as the post hoc test.
