APTT: activated partial thromboplastin time; NBVV: nonbleeding visible vessel; PT: prothrombin time; and SD: standard deviation.
*Thrombocytopenia is defined as platelet count <150000/mm3.
**Comorbid disease included old stroke, diabetes mellitus, liver cirrhosis, uremia, congestive heart failure, chronic pulmonary obstructive disease, and poststatus chemotherapy [15–21].
