Evidence for association between the HLA-DQA locus and abdominal aortic aneurysms in the Belgian population: a case control study

Table 5 Empirical and asymptotic p-values for comparisons between AAA cases and controls within each population and stratified by sex

AAA: abdominal aortic aneurysm; EP: empirical p-value; AP: asymptotic p-value.
^a Number of Belgian AAA cases: Male = 161, Female = 19; Canadian AAA cases: Male = 155, Female = 52; Belgian controls: Male = 178, Female = 91; Canadian controls: Male = 39, Female = 118.
^b Global empirical p-values were calculated by permutation test using the CLUMP [28] program.
^c Asymptotic p-values were calculated by χ² test.
