  1. The distribution of the examined dogs in the different age groups: All dogs < 0.16 years, D1, D2 and D3. The prevalence of distichiasis is given in the four age groups, including the standard error and the 95% confidence interval of the prevalence. The last column shows the odds of being affected with distichiasis in the different age groups
