The Kaplan–Meier survival analysis showed that the OS (P = 0.014; Figure 5(a)), DSS (P = 0.013; Figure 5(b)), DFI (P = 0.023; Figure 5(c)), and PFI (P = 0.001; Figure 5(d)) of cervical cancer patients with high PDIA3 expression were significantly lower than those with low expression, and patients with low PDIA3 expression had a longer survival time, suggesting that high PDIA3 expression was associated with a poor prognosis. Here, PDIA3 is linked to cervical carcinoma.
