Furthermore, there was a close association between AR and asthma in children with a history of asthma ( P <0.01, OR=4.88) or eczema ( P <0.01, OR=1.49), suggesting that both asthma and eczema were likely to be significant concomitant risk factors for AR. 37 Another recent random, multi-stage, cluster sampling study by Wang and colleagues 23 analyzed the correlation between AR and bronchial asthma or AD in a cohort of 1,524 individuals from several regions of northern China.
