a Each subject contributes two haplotypes to the analysis, thus, the total number of haplotypes in each column is twice the number of subjects.
b Wild allele is denoted by 1 and the polymorphic allele by 2. The order of the polymorphisms is as follows: codon 81, 284, and 762.
c Adjusted for age, sex, and pack-years.
d Adjusted for sex and pack-years.
e Adjusted for age and pack-years.
f Adjusted for age and sex.
g Current and former smokers.
h Pack-years.
i Nine large cell carcinomas were excluded.
