Correlation of plasma miR-21 and miR-93 with radiotherapy and chemotherapy efficacy and prognosis in patients with esophageal squamous cell carcinoma

Figure 3 Correlation of plasma miR-21 and miR-93 with 3-year overall survival of patients before radiotherapy and chemotherapy. A: Receiver operating characteristic (ROC) curve of miR-21 for assessing 3-year overall survival (OS); B: ROC curve of miR-93 for assessing 3-year OS; C: Correlation of miR-21 expression (≤ 5.60/> 5.60) with 3-year OS of esophageal squamous cell carcinoma (ESCC) patients; D: Correlation of miR-93 (≤ 3.87/> 3.87)with 3-year OS of ESCC patients.
