EGFR and astrocytoma (excluding glioblastoma): In addition, we observed the association between the EGFR and increased astrocytoma risk (Table 5), in the codominant model, genotype CC (rs730437, OR = 2.27, 95%CI: 1.26-4.10, p = 0.024; rs1468727, OR = 2.09, 95%CI: 1.17-3.72, p = 0.022); In the recessive model, genotype CC (rs730437, OR = 2.00, 95%CI: 1.17-3.41, p = 0.011; rs1468727, OR = 1.99, 95%CI: 1.22-3.24, p = 0.0062) and genotype GG (rs11506105, OR = 1.86, 95%CI: 1.07-3.23, p = 0.029).
