Fig. 5From: Tetraspanin profiles of serum extracellular vesicles reflect functional limitations and pain perception in knee osteoarthritisSchematic representation of the associations of selected extracellular vesicle (EV) subpopulations with different surface markers to physical performance, pain symptoms, and stiffness of the knee joint. Blue font color indicates that higher EV counts are associated with better physical function, less pain, and/or lower stiffness, whereas red font color indicates potentially aggravating factorsBack to article page
