TABLE 3.
Comparison of categorical accuracies for oxacillin and cefoxitin disk results when 1,761 S. aureus strains were tested in the dalbavancin in vitro study
| Cefoxitin susceptibility category | No. of strains (%) in indicated oxacillin susceptibility category
|
||
|---|---|---|---|
| Susceptible | Intermediate | Resistant | |
| Susceptible | 748 (42.6)a | 3 (0.2) | 1 (<0.1) |
| Resistant | 37 (2.3)b | 12 (0.7) | 957 (54.2)a |
a
Absolute categorical agreement was 96.8%, and minor errors were at only 0.9%.
b
Assuming cefoxitin results as presented in reference 7, very major (false-susceptible) errors were noted at 2.3%.
