Subsequently, through performing Cox regression analysis, 18 CRLs correlated with prognosis of COAD patients were uncovered, including AC015712.2, AC022210.1, AC025171.2, AC025171.4, AC067817.2, AC068205.2, AC107308.1, AL161729.4, AL356019.2, AP001619.1, EIF2AK3-DT, GABPB1-IT1, LINC00205, LINC01138, LINC02175, SNHG26, ZEB1-AS1, ZKSCAN2-DT (Fig. 3B). Here, ZKSCAN2 is linked to colon adenocarcinoma.
