Comparing participants included and excluded in these analyses.

Of the 14,062 participants, 8,365 had genetic data (after genetic quality control filters excluding individuals with incorrect sex assignments, minimal or excessive heterozygosity, disproportionate levels of missingness, cryptic relatedness, and non-European ancestry). 4,835 individuals had both genetic data and data on BMI and current asthma at 7–7½ y, and these individuals form the core sample for these analyses.*Chi-squared tests and t-test were used as appropriate.**General Certificate of Education level (school leaving certificate at 16 y) or lower, compared with A-level (qualification at 18 y) or degree level.在14062名研究参与者中，8365人拥有遗传数据（经遗传质量控制（genetic quality control）筛选，排除了性别分配错误、杂合度过低或过高、缺失比例异常、隐性亲缘关系以及非欧洲血统的个体）。其中4835人同时具备遗传数据，以及7至7.5岁时的身体质量指数（BMI，Body Mass Index）与当前哮喘患病情况的数据，该群体构成本次分析的核心样本。* 视情况采用卡方检验（chi-squared tests）与t检验（t-test）。** 以普通中等教育证书（General Certificate of Education，16岁时的离校资格证书）水平及以下者，与A-level（18岁时取得的资格证书）或学位水平者进行比较。
