AASK, African American Study of Kidney Disease and Hypertension; ARIC, Atherosclerosis Risk in Communities; SNP, single-nucleotide polymorphism.
Replication analysis was performed in the ARIC Study for associations that were determined to be novel (see Tables 3 and 4 and Supplementary Tables S3 and S4 for details).
