Also, for ACC, Cox regression results showed that the higher expression of CLDN6 had a worse prognosis, including OS (HR = 2.19, 95% CI: 1.01–4.75, p = 0.047) (Figure 6D), DSS (HR = 2.63, 95% CI: 1.14–6.06, p = 0.023) (Figure 6E), and PFI (HR = 2.10, 95% CI: 1.12–3.94, p = 0.021) (Figure 6F). The gene discussed is CLDN6; the disease is adrenal cortex carcinoma.
