| Outcome Measures: |
Primary: CKD at 12 months, To evaluate chronic kidney disease (CKD) progression at 12 months. The CKD progression is defined as an increase in CKD stage for at least 1 stage for at least 3 consecutive months during follow-up., 12 months | Secondary: Change in eGFR, calculated using the CKD Epidemiology Collaboration (CKD-EPI) equation expressed as a single equation: GFR (in mL/min/1.73 m2) = 141 × min (Scr /κ, 1)α × max(Scr /κ, 1)-1.209 × 0.993Age × 1.018 \[for the cases of females\] × 1.159 \[for the cases of ethnic Africans \]; where: Scr is the serum creatinine in mg/dL (equals to serum creatinine in micromole/L /88.4) , κ is 0.7 for females and 0.9 for males, α is -0.329 for females and -0.411 for males, min indicates the minimum of Scr /κ or 1, and max indicates the maximum of Scr /κ or 1.11 CKD stages 1, 2, 3A, 3B, 4 and 5 were defined based on eGFR, 12 months
