Single nucleotide polymorphisms (SNPs) markers are identified according to their standard rs numbers (NCBI build 36). We explored whether common genetic variants known to be related with physician-diagnosed asthma5 were associated with childhood FeNO. The total sample includes data of 14 independent GWA datasets (N = 8,858). MAF, minor allele frequency; S.E., standard error. β reflects differences in natural log-transformed FeNO per minor allele. P values are obtained from linear regression of each SNP against natural log-transformed FeNO adjusted for sex and age at time of measurement (fixed-effect additive genetic model). Derived inconsistency statistic I2 and HetP values reflect heterogeneity across studies with the use of Cochran's Q tests.
