A GFR of 9 mL/min/1.73 m2 corresponds to which stage of CKD?

Explanation:
CKD stages are determined by how much kidney function remains, as reflected by the estimated glomerular filtration rate (GFR). The thresholds are: stage 2 is 60–89, stage 3 is 30–59, stage 4 is 15–29, and stage 5 is less than 15. A GFR of 9 mL/min/1.73 m^2 falls below 15, placing it in stage 5 CKD. This stage is often referred to as end-stage renal disease, where kidney function is severely reduced and dialysis or transplantation is typically needed. The higher stages correspond to progressively greater remaining kidney function, so the other options would indicate better kidney function ranges.
