Table 3. Logistic regression analysis.

Variables	Logistic regression
	OR (95% CI)	p-value	c-statistics*
Disease duration	0.975 (0.955–0.995)	0.016*	0.749
Serum total IgE	1.001 (0.995–1.007)	0.769
MAST food	0.965 (0.798–1.168)	0.717

Bold denotes statistical significance (p<0.05).

Nagelkerke R²: 0.213; Hosmer & Lemeshow test: χ²=5.444 (p=0.709).

OR: odds ratio, CI: confidence interval, IgE: immunoglobulin E, MAST: multiple antigen simultaneous test.

^*c-statistics: area under the curve value of the logistic regression model.
