^aThe crude OR reported in Tables 2 and 3.

^bThe omnibus chi-square test of the genotype frequency distributions reported in Tables 2 and 3.

^cStatistical power was calculated using the number of observations in the study and the OR and P values in Tables 2 and 3.

^dCombined risk genotypes were to referred to ERCC2 rs238406 TG/TT + rs13181 TG/GG.
