The results showed that tumor size (HR, 6.181; 95% CI, 1.219-31.334; p = 0.028), lymphovascular invasion (HR, 5.910; 95% CI, 1.124-31.059; p = 0.036), and the high-GJA1 expression (HR, 4.084; 95% CI, 1.354-12.320; p = 0.013) were the important independent predictors of poor overall survival of CC (Figure 2 and Table 4). Here, GJA1 is linked to neoplasm.
