We correlated estimated GFR (CKD-EPI) and stage of chronic kidney disease (KDOQI) with circulating MGP, using multivariable linear and logistic regression. Results: Among Flemish and Africans, GFR averaged 89.5 and 110.9 mL/min/1.73 m2 and dp-ucMGP 3.68 and 7.0 [mu]g/L, respectiv...
For a doubling of dp-ucMGP, eGFR decreased by 1.5 (P = 0.023), 1.0 (P = 0.56), 2.8 (P = 0.0012) and 2.1 (P < 0.0001) mL/min/1.73 m2 in Flemish, white Africans, black Africans and all participants combined; the odds ratios for moving up one CKD stage were 1.17 (P = 0.033)...
