Packed cell volume of non-infected, mono-infected and co-infected dogs in the subset of animals tested by PCR for current infections (defined as DNA detection) with Ehrlichia canis and Anaplasma spp. (n = 85). Since only one dog each was mono-infected with A. phagocytophilum and co-infected with E. canis and A. phagocytophilum, respectively, these were not plotted. No mono-infections with A. platys were found in this data subset. Ends of the boxes define the 25th and 75th percentiles, with a line at the median and whiskers extending to 1.5 the interquartile range or up to the maximum/minimum value
