Same results were obtained for plasminogen activator inhibitor-1 (PAI-1) expression in these groups.16In a randomized controlled trial (RCT) of recovering MS patients, it was shown that plasma levels of TFPI17and other coagulation inhibitors (e.g., protein S) increased with increasing recovery rate and patients with a generally low level of TFPI in earlier disease states showed better rehabilitation afterwards.17 Here, TFPI is linked to myeloid sarcoma.
