Adjusted associations of perinatal characteristics with wheezing phenotypes in ALSPAC.

*compared with never/infrequent wheezing (N = 5642) and using each child’s phenotype probability as weights.
±Not adjusted for each other but adjusted for preterm delivery (<37 weeks).
‡Not adjusted for each other and not adjusted for birth weight/low birth weight (since birth weight does not influence gestational age).
+Chi-squared test across phenotypes.

* 以从未/偶发喘息者（N=5642）为参照组，并以每名儿童的表型（phenotype）概率作为权重。
± 未针对各因素彼此进行校正，但针对早产（胎龄<37周）进行了校正。
‡ 未针对各因素彼此进行校正，也未针对出生体重/低出生体重进行校正（因出生体重并不影响胎龄）。
+ 针对各组表型开展卡方检验（Chi-squared test）。
