Table 2

Serum 25 (OH) vitamin D status stratified by eGFR and albuminuria-to-creatinine ratio.

Mean eGFR, mL/min				<0.001
eGFR > 90 mL/min	607 (27.2%)	1227 (55.0%)	398 (17.8%)
eGFR 90–60 mL/min	619 (40.5%)	772 (50.5%)	139 (9.1%)
eGFR 60–45 mL/min	118 (54.1%)	79 (36.2%)	21 (9.6%)
eGFR < 45 mL/min	39 (39.0%)	46 (46%)	15 (15%)
Mean ACR ratio, g/g				0.2586
ACR < 30	1147 (32.8%)	1851 (53.0%)	497 (14.2%)
ACR 30–300	203 (43.5%)	220 (47.1%)	44 (9.4%)
ACR > 300	33 (28.0%)	53 (44.9%)	32 (27.1%)

eGFR: estimated glomerular filtration rate; ACR: urine albumin-to-creatinine ratio.
