Figure 3:
RFVs for PD-L1+ exosomes in plasma of patients with HNSCC stratified by disease activity and stage to create four patient groups: AD-UICC I/II, AD-UICC III/IV, NED-UICC I/II and NED-UICC III/IV. AD patients with high UICC stage had significantly increased RFVs for PD-L1+ exosomes in plasma compared to AD with low UICC stage or NED with low UICC stage.
