Table 2

Comparison of the β-endorphin concentrations and RQLQ scores among the three groups according to total IgE.

	β-Endorphin; (mean ± SD, pg/mL)	Total IgE
	27.22 ± 17.675	Less than 100 KU/L
	26.34 ± 14.46	100–200 KU/L
	24.67 ± 11.06	More than 200 KU/L

Data between groups were compared by single-factor ANOVA.
