BMC Veterinary Research

Table 8 Multivariate case-case comparisons of demographic risk factors between confirmed positive RHT herds, unconfirmed positive RHT herds, and unconfirmed inconclusive RHT herds

Variable	OR	95% CI	p-value	AUC
Confirmed positive RHT to Unconfirmed positive RHT
% of herd imported from high incidence regions	1.12	1.04 – 1.24	0.013	0.69
log₁₀ (Number of farms within 5 km radius)	0.19	0.05 – 0.61	0.006
Northing coordinate (100 km units)	0.65	0.46 – 0.90	0.012
Confirmed positive RHT to Unconfirmed inconclusive RHT
log₁₀ (Number of cattle present)	2.97	1.56 – 5.78	0.001	0.64
Easting coordinate (100 km units)	0.60	0.41 – 0.89	0.011
Unconfirmed positive RHT to Unconfirmed inconclusive RHT
log₁₀ (Number of farms within 5 km radius)	2.61	1.39 – 5.24	<0.001	0.57

The analysis included all Scottish cattle herds that were subject to RHT from 2002 to 2009.
