Which KDIGO CKD stage corresponds to an estimated GFR of 302 44 mL/min/1.73 m2?

Explanation:
Understanding the staging helps explain why this eGFR fits the answer. KDIGO divides CKD stages by estimated GFR, with Stage 3 further split into 3a (roughly 45–59) and 3b (roughly 30–44) to reflect different levels of kidney function and implications for management. An eGFR of 30–44 mL/min/1.73 m² sits in the 30s, which places it in Stage 3b. This indicates a more advanced decline than 3a but is still above the more severe Stage 4 range (15–29) and not in the normal-to-mild decline ranges of Stage 1 or Stage 2 (≥90 or 60–89).
