Associations between SNPs belonging to NOS2 and NOS3 and two quantitative phenotypes measured in the exhaled breath condensate (FeNO level and NO2–NO3 level) in non-asthmatic and asthmatic subjects–Single marker analysis.

In bold P-values surviving the adjustment (P≤0.0024 or P≤0.01 for NOS2 and NOS3 respectively).*Major allele was consider as baseline allele†MAF: Minor allele frequency#CI: confidence interval‡Analyses were conducted under an additive genetic model for NOS3 SNPs and under recessive or dominant genetic models for NOS2 SNPs and FeNO and EBC NO2–NO3 levels respectively.
