Changes in eGFR are shown as the means ± SD. Changes in UACR are expressed as the median values (25% value, 75% value). eGFR: estimated glomerular filtration rate; UACR: urinary albumin/creatinine ratio; CKD: chronic kidney disease; SBP: systolic blood pressure.
The numbers of patients per CKD stage are 111, 166, and 31 for CKD stages 1, 2, and 3 + 4 in the added treatment group and 104, 172, and 26 for these stages in the control group, respectively. The values were calculated by the Kruskal Wallis test for the change in eGFR and UACR and one-way analysis of variance for the change in morning SBP.
