Table 1 Prevalence of the 70 most common disorders (at least 100 events) at a precise-level of diagnostic precision recorded in dogs (n = 22,333) under primary-care veterinary care at UK practices participating in the VetCompass™ Programme from January 1st to December 31st, 2016. The odds ratio and P-values reflect the odds in males compared to females, and the odds in neutered dogs compared to entire dogs. P-values less than 0.05 shown in bold. *CI confidence interval
