AAA: abdominal aortic aneurysm.
^a Number of alleles.
^b Empirical P = 0.019, asymptotic P = 0.003 for comparison of this particular allele versus all other alleles combined between cases and controls among Belgian males.
^c Empirical P = 0.033, asymptotic P = 0.005 for comparison of this particular allele versus all other alleles combined between cases and controls among Belgians.
