Table 3.
Breeds that were significantly more likely to demonstrate bronchiectasis at the UCD VMTH. The observed:expected (O:E) ratio provides a comparison of the number of affected dogs for a particular breed in relation to the expected number of cases for that breed based on the distribution of all breeds seen at the VMTH during the time frame of this study. P value corresponds to the null hypothesis that the O:E ratio = 1 and is calculated from the breed's cell‐specific chi‐square contribution for bronchiectasis diagnosis to the overall chi‐square test statistic for all breeds
