Cohen’s κ coefficients for sedimentation/flotation, Mini-FLOTAC and FECPAK^G2 compared to the gold standard in 1067 equine faecal samples

Method	No. positive gold standarda (frequency)	No. positive	No. false negative	Percentage of positive samples detected false negative	Cohen’s κ
Strongyle eggs	524 (49.1%)
Mini-FLOTAC		436	88	16.8	0.83
Sed/flo		496	28	5.3	0.95
FECPAKG2		317	207	39.5	0.61
Parascaris spp. eggs	55 (5.2%)
Mini-FLOTAC		43	12	21.8	0.87
Sed/flo		49	6	10.9	0.94
FECPAKG2		20	35	63.6	0.52
Anoplocephalidae eggs	31 (2.9%)
Mini-FLOTAC	31	28	3	9.7	0.97
Sed/flo		29	2	6.5	0.95

^aThe gold standard was defined by counting every sample as positive that was diagnosed positive in at least one sample
