Figure 4. ROC analyses substantiate the diagnostic power of the CD9⁺ and CD82⁺ EV concentration measurements within synovial liquids for the discrimination of aseptic endoprosthesis loosening and PJI. ROC curves of the individual CD9 and CD82 EV concentration values in comparison to the reference line. Red squares show the results of the ROC analysis. Drawing Software: GraphPad. EV: Extracellular vesicle; PJI: periprosthetic joint infection; ROC: receiver operating characteristic.
