Significant values are indicated in bold characters. TIPIN rs3759786, TIPIN rs6494568, and TIPIN rs12323975 were not assessed with recessive genetic model because there were no patients having homozygous genotype of the recessive allele in these SNPs.
CI confidence interval, HR hazard ratio, NA not assessed, OS overall survival, SNP single nucleotide polymorphism.
aP-values were based on log-rank test.
bP-values were based on Wald test in the multivariate Cox proportional hazards regression model.
