Low molecular weight heparin vs vitamin K antagonist (VKA)

Thrombocytopenia (up to 3 months)n · people with cancer with thrombosis prophylaxis and central venous catheters

Low‐molecular‐weight heparin (LMWH) probably leads to higher thrombocytopenia (up to 3 months)n compared with vitamin K antagonist (VKA) (moderate certainty).
