The denominators of the essential agreement (EA) were less than the total number of the isolates tested because MIC results of some isolates were out of the drug concentration ranges, and thus, the EA cannot be determined.
The EA cannot be determined because the MIC results were out of the drug concentration ranges.
S, susceptible; I, intermediate, R, resistant; EA, essential agreement, CA, category agreement; VME, very major error, ME, major error, MiE, minor error; N/A, not available; TMP-SMX, trimethoprim-sulfamethoxazole.
