Figure 2
Factorial analysis of the complete dataset using a first-order factor model. The diagram represents the items that make up the two factors and their respective factor loadings in behavioural activities with the corresponding values. Positive correlations with the corresponding value load are represented in black. Negative correlations with the corresponding value load are represented in red. The mean of absolute values is under each factor heading. Factor one (RC1) contained four variables associated with demographic factors, namely: origin, housing (p1), breed, and outcome (presence or absence of parasitism). Factor two (RC2) contained five variables associated with the clinical signs of dogs, namely: weight loss (p11), diarrhoea (p9), dull fur (p12), abdominal distension (p13), and emesis (p10). For factor two, the inversely correlated variables were routine consultation (p5), endo (p7) and ectoparasiticide treatment (p8), sex, and age.
