In the stratified analysis, expression status of GLUT1 was associated with unfavorable clinical results of oral squamous cell carcinoma (OR: 3.79; 95% CI, 1.74–8.24, P = 0.0008) (Figure 3A), and breast carcinoma (OR: 2.32; 95% CI, 1.02–5.30, P = 0.04) (Figure 3B). Here, SLC2A1 is linked to breast carcinoma.
