Categories of eGFR.

eGFR category	HbSS 𝑛 =60 (%	HbAA 𝑛 =60 (%)	Total 𝑛 =120	Statistical test
Hyperfiltration	10 (16.7)	0 (0.0)	10 (8.3)
Normal	47 (78.3)	58 (96.7)	105 (87.5)	Fishers
Mildly decreased	3 (5.0)	2 (3.3)	5 (4.2)

Key: hyperfiltration (high) and normal: eGFR category G1 (≥90 ml/min/1.73 m²), mildly decreased: eGFR category G2 (60-89 ml/min/1.73 m²). None of the study population was in categories G3a–G5 (<60 ml/min/1.73 m²).
