Distribution of NFE2L2 (rs6721961) and NQO1 (rs1800566) SNPs categorized by BPD outcomes in Caucasians:

Variant rs number	No BPD (n=255) genotype frequency (%)	All BPD (n=220) genotype frequency (%)	Severe BPD (n=101) genotype frequency (%)

NFE2L2 rs6721961	CC - 186 (74.9)	CC - 176 (80.0)^†	CC - 88 (87.1) ^‡
	CA - 69 (25.1)	CA - 40 (18.2)	CA - 11 (10.9)
	AA - 0	AA - 4 (1.8)	AA - 2 (2)

NQO1 rs1800566	CC - 154 (60.4)	CC - 131 (59.3)	CC - 63 (62.4)
	CT - 94 (36.9)	CT - 73 (33.0)	CT - 30 (30.6)
	TT - 7 (2.7)	TT - 17 (7.7) ^*	TT - 8 (7.5)

P=0.07 (BPD vs. infants without BPD; dominant model);

^‡

P=0.004 (severe BPD vs. infants without severe BPD; dominant model);

P=0.014 (BPD vs. infants without BPD; recessive model).
