Definitions for kidney function categories with and without risk factors and heavy proteinuria

eGFR categories (ml/min/1.73m2)	Participant subsets
	All participants	Subset 1: no DM, HTN, or heavy proteinuria	Subset 2: no DM, HTN, heavy proteinuria, or HIV
≥ 90 (normal kidney function)	Normal eGFR	Normal eGFRDEGREE	Normal eGFRKenya
≥ 60 to < 90 (mild kidney dysfunction)	Reduced eGFR	Reduced eGFRDEGREE	Reduced eGFRKenya
< 60 (moderate or established kidney dysfunction)	Proxy of CKDa	CKDuDEGREE	CKDuKenya

^aNo case would be considered CKD because serum creatinine was measured only on one occasion
