Associations between receiving tick antitoxin serum (TAS) and mortality by day 5 after presentation to the Animal Emergency Service in cats with tick paralysis unadjusted and adjusted for confounding by initial gait score, initial respiratory score and rectal temperature

Received TAS	No. of cases	% (n) died by day 5	OR adjusted for	OR	95% CI	P value*
Yes	1410	2.0 (28)		Ref. group
No	52	7.7 (4)	No adjustments	4.1	1.4–12.2	0.011
			Initial gait score	8.2	2.4–27.6	0.001
			Initial respiratory score	10.6	3.2–34.9	<0.001
			Body temperature at presentation	13.3	3.6–49.7	<0.001

^*Wald P values for ‘No’ relative to the reference group (‘Yes’); all likelihood ratio test P values were <0.001

OR = odds ratio; CI = confidence interval; Ref. group = reference group
