We found that ERCC2 rs13181 A allele and GG genotype were associated with overall survival of osteosarcoma, but AA genotype not (A allele: OR = 0.78, 95% CI: 0.65–0.93, P = 0.007; G G genotype: OR = 1.32, 95% CI: 1.05–1.65, P = 0.02; AA genotype: OR = 0.69, 95% CI: 0.45–1.04, P = 0.08; Figure 5). Here, ERCC2 is linked to osteosarcoma.
