A treatment-related adverse event was any untoward medical occurrence attributed to sildenafil citrate in a participant who received sildenafil citrate. A treatment-related serious adverse event was a treatment-related adverse event resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; lifethreatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Relatedness to sildenafil citrate was assessed by the physician/investigator.
Time frame: 3 years
A treatment-related adverse event was any untoward medical occurrence attributed to sildenafil citrate in a participant who received sildenafil citrate. Expectedness of the adverse event was determined according to the Japanese package insert. Relatedness to sildenafil citrate was assessed by the physician/investigator.
Time frame: 3 years
A treatment-related adverse event was any untoward medical occurrence attributed to sildenafil citrate in a participant who received sildenafil citrate. Relatedness to sildenafil citrate was assessed by the physician/investigator. Participants with treatment related adverse events were counted by age to assess whether it was risk factor for the treatment related adverse events.
Time frame: 3 years
A treatment-related adverse event was any untoward medical occurrence attributed to sildenafil citrate in a participant who received sildenafil citrate. Relatedness to sildenafil citrate was assessed by the physician/investigator. Participants with treatment related adverse events were counted by gender to assess whether it was risk factor for the treatment related adverse events.
Time frame: 3 years
A treatment-related adverse event was any untoward medical occurrence attributed to sildenafil citrate in a participant who received sildenafil citrate. Relatedness to sildenafil citrate was assessed by the physician/investigator. Participants with treatment related adverse events were counted by disease type to assess whether it was risk factor for the treatment related adverse events.
Time frame: 3 years
A treatment-related adverse event was any untoward medical occurrence attributed to sildenafil citrate in a participant who received sildenafil citrate. Relatedness to sildenafil citrate was assessed by the physician/investigator. Participants with treatment related adverse events were counted by severity (WHO functional classification for PAH range;This system grades PAH severity according to the functional status of the patient. The grades range from Functional Class (FC) I, where the patient's disease does not affect their day-to-day activities, to FC IV, where patients are severely functionally impaired, even at rest. This functional classification system links symptoms with activity limitations, and allows clinicians to quickly predict disease progression and prognosis, as well as the need for specific treatment regimens, irrespective of the underlying etiology of PAH) to assess whether it was risk factor for the treatment related adverse events.
Time frame: 3 years
Clinical effectiveness rate, which was defined as the percentage of participants who achieved clinical effectiveness over the total number of assessable effectiveness analysis population, was presented. Clinical effectiveness of sildenafil citrate was assessed as "effective," "ineffective" or "unassessable" by the physician/investigator. Overall effectiveness of sildenafil citrate was determined by the physician/investigator based on clinical symptoms, laboratory values, and other examinations such as echocardiogram. Participants achieved clinical effectiveness by age were counted to assess whether it contributes to the clinical effectiveness.
