  • Number of Participants Experiencing Cardiovascular Composite Outcomes [ Time Frame: Within 5 years ]
    Number of participants experiencing the first occurence of any of the following: Cardiovascular death; non-fatal stroke; non-fatal myocardial infarction; hospitalization for unstable angina; lower extremity amputation; coronary/carotid/peripheral revascularization.
  • The Change in Proteinuria [ Time Frame: Randomization to 5 years ]
    The median percentage change from baseline value in urinary protein:creatinine ratio
  • Reciprocal (1/Serum Creatinine) of Serum Creatinine [ Time Frame: Randomization to 5 years ]
    The amount of serum creatinine was determined by blood tests periodically during the study. The amount of creatinine is an indication of kidney function. The reciprocal of serum creatinine is used in an equation to determine the change in kidney function from baseline. The reciprocal of the serum creatinine was monitored to detect kidney function changes over duration of the study.
  • 1. First occurrence of any of the following:
  • Cardiovascular death
  • non-fatal stroke
  • non-fatal myocardial infarction
  • hospitalization for unstable angina
  • hospitalization for heart failure
  • coronary/carotid/periperal revascularization
  • lower extremity amputation
  • 2. change in proteinuria
  • 3. reciprocal of serum creatinine
