Table 4.

Simple descriptive scale (SDS) scores in group nA (normal reproductive status) and rA (pregnant or in oestrus). Table shows percentage of group with SDS scores of 0, 1 and 2 pre-operatively, and 4 and 24 h postoperatively. Friedman and Dunn’s test for within-group changes, χ² test for comparison between groups

SDS score (%)		0 (%)	1 (%)	2 (%)	Difference from pre-operation	Difference K vs A

	4 h postoperative	9	58	33	P <0.01	NS
	24 h postoperative	63	26	11	P <0.05	NS
