Abbreviations: SNP, single nucleotide polymorphism; OR, odds ratio, CI, confidence interval.
Odds ratios omitted where numbers were insufficient for calculation.
Bold indicates significance level (P-value) below 0.05.
Haplotypes defined by SNP alleles in chromosomal order from 5’ to 3’ across the CXCL12 gene region (rs17885289, rs2839685, rs17880313, rs7092453, rs2236534, rs266085, rs1801157, rs3740085, rs266093), where zero (0) indicates the common allele and one (1) indicates minor allele.
Cases include squamous cell carcinoma (n=376 subjects), invasive adenocarcinoma (n=169 subjects), adenocarcinoma in situ (n=339 subjects), and adenosquamous carcinoma (n=31 subjects).
Risk estimates include all races, adjusted for age (categorically, as presented in Table 1) and race (white versus nonwhite).
