Patients with hemophilia B (congenital blood coagulation factor IX deficiency) who are administered this drug. Patients with hemophilia B are either patients for whom treatment was already started with a blood coagulation factor IX product (Previously treated patients: hereinafter, PTPs) or patients who have no history of treatment with a blood coagulation factor IX product in the past and for whom treatment will be started with this drug for the first time (Previously untreated patients: hereinafter, PUPs).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Bleeding Episodes (Annual Bleeding Event Rate) During Periodic Replacement Therapy | Annual bleeding rate (ABR) was calculated as the number of total bleeding events occured during prophylaxis period devided by the period (events/year). ABR for other replacement treatment period was also calculated to evaluate the differences between types of treatment. If the period used for ABR calculation was less or equal than 7 days, the relevant data was regarded as missing. | 2 years for PTPs, 1 year for PUPs | 
| Number of Administrations Required for Hemostasis for Bleeding Events | Mean number of administrations for hemostasis in replacement therapy for bleeding events. | 2 years for PTPs, 1 year for PUPs | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Subjective Evaluation of Each Therapeutic Administration for Bleeding Episodes | Propotion of subjects whose physicians evaluated the effect of BeneFIX for bleeding episodes as excellent or good was calculated. | 2 years for PTPs, 1 year for PUPs |
