aSample sizes are as follows (microalbuminuria case numbers in parentheses): CKDGen Stage 1: 31580 (3698); CARe European Americans: 19,499 (2100); CKDGen Stage 2: 27,746 (3313); CARe African Americans: 6981 (1159).
bP values from CKDGen and CARe European and African American Stage 1 analyses are from the inverse variance weighted fixed effects method, and P values from the CKDGen Stage 2 analyses, the combined analyses, and the hypertension- and diabetes-stratified analyses are from the sample size weighted Z score method. In all analyses, the minor allele C showed an increase in UACR, direction consistent with the odds ratio for MA.
cP values from inverse variance weighted fixed effects model.
dCombined populations of European ancestry, includes CKDGen Stages 1 and 2 (after removal of ARIC, CHS, and FHS) and all five cohorts of CARe European Americans: 63,153 (7383 microalbuminuria cases).
eCombined populations of European ancestry, includes CKDGen Stage 1 (after removal of ARIC, CHS, and FHS) and all five cohorts of CARe European Americans: 36,166 (4128 microalbuminuria cases).
fModeled as hazard ratio; n = 1304 including 318 cases of persistent microalbuminuria and 116 cases of severe nephropathy.
