Asthma	Cigarettes per Day	65	3.43×10−4	1.24	(1.10,1.39)
Asthma	Age Of Smoking Initiation	67	9.09×10−6	1.26	(1.14,1.39)
Asthma	PM 2.5	70	1.34×10−6	1.26	(1.15,1.39)
Asthma	Age Of Smoking Initiation/Cigarettes per Day/smoking initiation/PM 2.5	62	1.19×10−4	1.22	(1.10,1.35)

COPD, chronic obstructive pulmonary disease; SNPs, single nucleotide polymorphisms; OR, odds ratio; CI, confidence interval.
