Table 7.
The proportion of the dogs present in each category of the categorical variable “life events” (with the percentage expected by chance in brackets), presented separately for dogs in the trauma group (No and Yes).
| Factor | Category | Previous trauma | Statistics | |
|---|---|---|---|---|
| No | Yes | |||
| Life events | None | 30 (22)a | 11 (22)b | |
| One | 38 (32)a | 25 (32)b | ||
| Two | 23 (26)a | 29 (26)b | χ(3) = 162.672 | |
| Three or more | 9 (20)a | 35 (20)b | P < 0.001 | |
Where a significant group difference was found the category with the larger or smaller proportion than was expected by chance is marked in bold. Z-tests were performed to compare column proportions (P-values were adjusted for multiple comparison using the Bonferroni method). Each subscript letter denotes a subset of previous trauma category whose column proportion did not differ significantly from each other at the 0.05 level.
