Table 4 Results of LMMs testing the influence of animal sex, age and current infections (as defined by DNA detection) with Ehrlichia canis and Anaplasma platys (Model A) as well as A. phagocytophilum (Model B) on packed cell volume (PVC) of 85 dogs from Nicaragua

From: Seroprevalence and current infections of canine vector-borne diseases in Nicaragua
