Table 1 Analysis of correlation and categorical agreement levels between Etest and Sensititre kit (broth microdilution method) as methods for susceptibility testing of Campylobacter isolates to tetracycline, erythromycin, and ciprofloxacin, using Sensititre and Etest methods

From: Antimicrobial susceptibility of Campylobacter jejuni and Campylobacter coli: comparison between Etest and a broth dilution method

Antibiotic agent Percentage of categorical agreement Kappa coefficient r (p value) Pearson correlation coefficient (p value)
Tetracycline 97 0.653 (< 0.0001) 0.645 (< 0.0001)
Erythromycin 98.5 0.66 (< 0.0001) 0.588 (< 0.0001)
Ciprofloxacin 100 1 (< 0.0001) 0.865 (< 0.0001)
