Overall survival and disease-free survival according to each genotype.

Abbreviations: 5Y-OSR, 5-year overall survival rate; 5Y-DFSR, 5-year disease-free survival rate; HR, hazard ratio; CI, confidence interval.*Column percentage.†Row percentage.‡5Y-OSR and 5Y-DFSR, proportion of survival derived from Kaplan-Meier analysis.¶HRs, 95% CIs and their corresponding P-values were calculated using multivariate Cox proportional hazard models, adjusted for age, gender, smoking status, tumor histology, and pathologic stage.#These SNPs were selected from our previous studies: rs967591 [9]; rs1047266 [10]; and rs3803300 [11]; rs2287845 and rs3756585 [15]Overall survival and disease-free survival according to each genotype.
