^aTwo control groups were considered. Control 2 (C2, n = 80) contained all dogs free from SPAID, irrespective of age, whilst Control 1 (C1, n = 34) included only those individuals older than 60 months with no signs of SPAID. The counts required to calculate the receiver operator curve (ROC) area are reported, including true positive (TP) and false positive (FP)
