Longitudinal protein abundances among never responders who do and do not develop VTE. Median plasma protein levels with standard error across monitored time points, categorized by VTE development status: no VTE and VTE (purple). The analysis specifically focused on patients who responded poorly to enoxaparin treatment. (A) Fibrinogen chain levels. (B) Carboxypeptidase N catalytic chain. (C) Coagulation factors. (D) Complement activators. (E) Complement proteins. (F) Acute phase proteins. (G) VWF.
