UBE2D2 and neoplasm: Analysis of the clinical information table was performed (Table 2), which clarified that circ-UBE2D2 was correlated with tumor node metastasis (TNM) staging and lymph node metastasis, and elevated circ-UBE2D2 predicted a poor prognosis (HR = 1.80; P < 0.05; 95% CI, 0.32–1.41) (Figure 1(b)).
