Notes: CKD stage 1A: ≥130 mL/min/1.73 m2; 1B: 90 mL/min/1.73 m2 to <130 mL/min/1.73 m2; 2: 60 mL/min/1.73 m2 to <90 mL/min/1.73 m2; 3: 30 mL/min/1.73 m2 to <60 mL/min/1.73 m2; 4/5: 0 to <30 mL/min/1.73 m2. Change is calculated based on mean values. All CIs are calculated based on the mean (descriptive or least squares).
Abbreviations: BL, baseline; CI, confidence interval; CKD, chronic kidney disease; eGFR, estimated glomerular filtration rate; EOW, every other week; SD, standard deviation.
