Table 3 Multivariable logistic regression odds ratios with corresponding 95% CI (confidence interval) for the combined list from the 30 most common disorders in Pugs and the 30 most common disorders in non-Pugs at a grouped-level of diagnostic precision recorded in dogs under primary veterinary care at UK practices participating in the VetCompass™ Programme from January 1st 2016 to December 31st, 2016. The results are adjusted for the effects of 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
