Table 3.
Pairwise comparison of antibiotic resistance from each country. (Note: for each significant pair, p value ( ) is given under the larger proportion.) Note that New Zealand displayed a significantly greater antibiotic susceptibility than did Argentina and England. Multidrug resistance was prevalent among all centers, with no significant difference. Vancomycin resistance was seen only in England and Canada.
