Fig. 3From: Extracellular volume fraction measurement correlates with lymphocyte abundance in thymic epithelial tumorsa Box and whisker plots show comparison of ECV fractions of TETs based on lymphocyte abundance. Higher ECV was found in lymphocyte sparse TETs than in lymphocyte abundant TETs (p < .001). b Receiver operating characteristic (ROC) curve shows the cutoff ECV value used to differentiation between the lymphocyte sparse and lymphocyte abundant groups was 36.0%, with sensitivity 92.3%, specificity 94.4%, and area under the curve of 0.97Back to article page
