Table 3 Multivariable logistic regression odds ratios with corresponding 95% confidence interval (CI*) for the combined list from the 30 most common disorders in English Bulldogs and in dogs that are not English Bulldogs at a grouped-level of diagnostic precision recorded in dogs under primary veterinary care at UK practices participating in the VetCompass™ Programme from January 1^st 2016 to December 31^st, 2016. Model variables accounted for included age, sex-neuter status, at/above or below mean bodyweight, insurance status and vet group. Grouped-level precision describes the original extracted terms mapped to a general level of diagnostic precision
