12-Month cumulative incidence (95% CI).
Moderate albuminuria: 30–299 mg/g.
Severe albuminuria: 300–999 mg/g.
Very severe albuminuria: ≥1,000 mg/g.
Based on a combination of age, albumin-creatinine ratio, and eGFR thresholds (see Table S2).
Type of test at first detection for individuals with newly detected albuminuria, and type of test at albuminuria confirmation for individuals with confirmed albuminuria.
Estimated GFR < 30 mL/min per 1.73 m2 or refractory hypertension after newly detected albuminuria; eGFR < 30 mL/min per 1.73 m2, refractory hypertension or sustained albuminuria ≥ 300 mg/g at retesting.
