Inclusion flowchart for evaluation of the blood neutrophil-to-lymphocyte ratio (NLR) as a diagnostic marker in dogs with chronic enteropathy. Of the 287 dogs considered for inclusion in the study, we included 93 dogs. I. Data from all 93 dogs were included in the first part of the study (I.a–c), but prospective canine chronic enteropathy clinical activity index [CCECAI] scores (I.b) and histologic lesion scores (I.c) were only available from a subset of those dogs. II. Complete follow-up information used for the second part of the study (II) was available from 41 dogs.
