Relative circ-DLG1 expression and its clinical significance in ESCC plasmas and tissues.

Notes: (A) The expression of circ-DLG1 levels was significantly higher in ESCC plasmas than that in normal plasmas. (B) The expression of circ-DLG1 expression levels was significantly higher in ESCC tissues than that in adjacent noncancerous tissues. (C) The AUC of distinguishing ESCC plasmas from healthy controls was 0.6480. (D) The expression level of circ-DLG1 was significantly associated with TNM stage. ***P<0.0001, *P<0.05.

Abbreviations: AUC, area under the ROC curve; ESCC, esophageal squamous cell carcinoma.
