Table 5 Significant results of two multivariate regression models: 1) A binary logistic regression model of the associations between GI parasite presence and dog demographic and exposure dimensions and age, breed, gender, and park management variables; 2) A negative binomial regression model of the associations between GI parasite median intensity and dog demographic and exposure dimensions and age, breed, gender, and park management variables

  1. aThe reference category for the dependant variable is 0 where 0 = negative and 1 = positive for parasites.
  2. bB value magnitude and direction is the slope of the line and indicates the chance that a given dog has a value of 1 relative to the component loadings or independent variables.
  3. cB value magnitude and direction is the slope of the line and indicates the direction of infection intensity of a given dog relative to the component loadings or independent variables.
