aSuccessful replication was defined as consistent direction of association in GOLDN and ARIC and P-value of <0.05/164 (<3 × 10−4) in the replication cohort. Meta-analysis used Stouffer's Z for trend test, which is based on meta-analysis of P-values with adjustment for cohort sample size and direction.
