Comparison of FECPAKG2, a modified Mini-FLOTAC technique and combined sedimentation and flotation for the coproscopic examination of helminth eggs in horses

Table 2 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 standard^a (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
FECPAK^G2		317	207	39.5	0.61
Parascaris spp. eggs	55 (5.2%)

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