Prospective serological and molecular cross-sectional study focusing on Bartonella and other blood-borne organisms in cats from Catalonia (Spain)

Table 2 Comparison of agreement between IFAs performed against three Bartonella species

Test pair	κ ± SE	κ interpretation^a
B. henselae IFA versus B. quintana IFA	0.661 ± 0.070	Substantial agreement
B. henselae IFA versus B. koehlerae IFA	0.889 ± 0.048	Almost perfect agreement
B. quintana IFA versus B. koehlerae IFA	0.726 ± 0.065	Substantial agreement

^aThe interpretation for each κ value is shown in the final column according to the following scale: ≤ 0, no agreement; 0.01–0.20, none to slight; 0.21–0.40, fair; 0.41–0.60, moderate; 0.61–0.80, substantial; and 0.81–1.00, almost perfect agreement. IFA, immunofluorescence antibody assay; κ, Cohen’s kappa value; SE, standard error
