Correlation between Preoperative Anxiety and ABO Blood Types: Evidence from a Clinical Cross-Sectional Study

Table 3

Binary logistic regression analysis of factors correlated with VA scores.

Variables	Response	Odds ratio (95% CI)	value
Age		1.00 (0.97-1.02)	0.71
Sex	Male	1
	Female	3.73 (2.32-6.00)	<0.001
ASA	I	1
	II	0.36 (0.21-0.63)	<0.001
	III	0.41 (0.20-0.86)	0.019
VAS		1.25 (1.11-1.41)	<0.001
Blood types	AB	1
	A/B/O	0.28 (0.16-0.49)	0.001

Note: backward LR was used in binary logistic regression analysis of factors correlated with VA scores. In the binary logistic regression model, VA scores ranging from 1 to 4 were set at zero, with 169 patients. VA scores ranging from 5 to 10 were set at one, with 183 patients. Significant difference, (). ASA = American Society of Anesthesiologists; VAS = visual analogue scale for pain.
