Control group for AR: among subjects who visited hospital, the subjects who have never been diagnosed with AR by physician.
AR, allergic rhinitis; ARIA, Allergic Rhinitis and its Impact on Asthma; aOR, adjusted odds ratio; CI, confidence interval; SPT, skin prick test.
*Adjusted by sex, maternal education levels, parental history of allergic diseases, history of second-hand smoking, residential area, and economic status; †P < 0.05; ‡P < 0.01.
