As shown in Figure 2A, univariate Cox regression analysis of the results from 33 types of cancer revealed that RCOR1 expression was unfavorably associated with OS of ACC (HR = 2.31, 95% CI 1.30–4.10), BLCA (HR = 1.38, 95% CI 1.10–1.74), LIHC (HR = 1.41, 95% CI 1.02–1.94), LAUD (HR = 1.40, 95% CI 1.05–1.86) and PCPG (HR = 2.64, 95% CI 1.03–6.76) (p < 0.05). Here, RCOR1 is linked to adrenal cortex carcinoma.
