Outcome Measures

Primary Outcomes (1)

  • Renal function decline

    Renal function decline was defined based on one of more of the following : (1) A certain drop in eGFR, was defined as a drop in GFR category (≥90\[G1\], 60-89\[G2\], 45-59\[G3a\], 30-44\[G3b\], 15-29\[G4\], \<15\[G5\] ml/min/1.73m2) accompanied by a 25% or greater drop in eGFR from baseline; (2) Rapid progression, was defined as a sustained decline in eGFR of more than 5 ml/min/1.73m2/yr.

    Serum creatinine was examined at baseline and at the final visit (5 years) of the trial.

Secondary Outcomes (4)

  • Average decline rate in eGFR (ml/min/1.73m2/yr).

    Serum creatinine was examined at baseline and at the final visit (5 years) of the trial.

  • New-onset chronic kidney disease based on eGFR(eGFR<60 ml/min/1.73 m2)

    Serum creatinine was examined at baseline and at the final visit (5 years) of the trial.

  • New-onset albuminuria

    Albuminuria was examined at baseline and at the final visit (5 years) of the trial.

  • A composite of renal events.

    Every 3 months during the trial, up to 5 years
