* Laboratory data abnormality suggesting thrombocytopenia.
– Laboratory data were not available.
#1 Laboratory data were assessed upon the patient's arrival at the emergency room.
#2 Laboratory data were checked 2 h after transfusion with 12 units of platelets on the first hospitalization day.
#3 Laboratory data were examined before discharge on the 4th hospitalization day.
#4 Laboratory data were assessed at the outpatient department.
