We investigated the association between TEDC2 expression and OS in tumours (Figure 3A), and the results showed that high expression of TEDC2 was associated with significantly shorter OS in ACC (HR = 7.129, 95% CI 2.838–17.907, p < 0.001) , KIRC (HR = 1.843, 95% CI 1.358–2.5, p < 0.001), LUAD (HR = 1.681, 95% CI 1.256–2.251, p < 0.001) and LIHC (HR = 2.026, 95% CI 1.421–2.888, p < 0.001) (Figure 3B). The gene discussed is TEDC2; the disease is adrenal cortex carcinoma.
