As shown in Table 3, the univariate Cox regression analysis showed that FOXD1 expression (HR =0.750, 95% CI: 0.572-0.983, P =0.037), distant metastasis (HR =3.099, 95% CI =1.266-7.584, P =0.013), clinical stages (HR =1.557, 95% CI =1.131-2.144, P =0.007), tumor size (HR =1.651, 95% CI =1.195-2.281, P =0.002), and smoking history (HR =0.656, 95% CI =0.494-0.872, P =0.004) were associated with OS. Here, FOXD1 is linked to neoplasm.
