Note: Isolated diastolic: diastolic blood pressure (BP) > 80 mm Hg with systolic BP ≤ 130 mm Hg, Normotension: systolic BP ≤ 130mm Hg and diastolic BP ≤ 80 mm Hg, isolated systolic hypertension: systolic BP >130 mm Hg and diastolic BP ≤ 80 mm Hg, and systolic diastolic hypertension: systolic BP >130 mm Hg and diastolic BP >80 mm Hg.
CKD stages: Stage 1: eGFR ≥ 90 mL/min/1.73 m2; Stage 2: eGFR 60-89 mL/min/1.73 m2; Stage 3a: eGFR 45-59 mL/min/1.73 m2; Stage 3b: eGFR 30-44 mL/min/1.73 m2; Stage 4: eGFR 15-29 mL/min/1.73 m2; and Stage 5: eGFR <15 mL/min/1.73m2.
