Combined effect of 8 SNPs on overall survival and disease-free survival.

Abbreviations: 5Y-OSR, 5-year overall survival rate; 5Y-DFSR, 5-year disease-free survival rate; PL-R, log-rank P; 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.#For additive genetic model, score value 1 assigned for low risk, 2 for intermediate risk, 3 for high risk genotype among WW, WV and VV genotypes; For dominant genetic model, 1 for low risk, 3 for high risk genotype among WW and WV+VV genotypes; For recessive genetic model, 1 for low risk, 3 for high risk genotype among WW+WV and VV genotypes (W, wild allele; V, variant allele)Combined effect of 8 SNPs on overall survival and disease-free survival.
