Plasma MicroRNA-21 Predicts Postoperative Pulmonary Complications in Patients Undergoing Pneumoresection

Figure 2

In a receiver operative characteristic (ROC) curve analysis, the area under the curve (AUC) of miRNA-21 levels during surgery for PPCs was 0.838 (95% CI, 0.782–0.894; ). At a cutoff value of 1.745, miRNA-21 had a sensitivity of 68.4% and a specificity of 70.6% for predicting PPCs within 7 days after surgery.
