a Statistically significant P values are in boldface type.
b All isolates (n = 160) analyzed as a single group.
#These comparison were only done in KH; for AH and combined we looked at i, s, and m regions of vacA separately, which wasn’t feasible with KH since was overwhelmingly s1/i1/m1.
*All KH strains are vacA s1.
$AB&Other refers to any cagA EPIYA motif that is not ABC(1–4), or ABD.
