Figure 1. Test –retest reliability evaluation of clinician-based feline orofacial cancer pain scoring (UFEPS/VET).

(A) The difference between two replicates of the UFEPS/VET are plotted against the mean of both repeats. The dashed line represents a bias of 0.5556; the dotted lines represent the 95% limits of agreement (LoA ), 4.602 and −3.491. (B) The two scores had good and significant correlation (r² = 0.77, P < 0.0001). Each dot represents an individual cat; open dots denote healthy control cats; closed/solid dots denote cats with sublingual SCC.
