结局指标
主要结局
Number of Participants With Treatment-emergent Adverse Events (TEAE)
时间窗: Approximately up to 54 months
Percentage of Participants With TEAE
时间窗: Approximately up to 54 months
The percentage of participants was rounded to one place of decimal.
Number of TEAE
时间窗: Approximately up to 54 months
TEAE Rates Per Injection
时间窗: Approximately up to 54 months
The TEAE rate per injection was calculated as the number of TEAE/ total number of injections. The number of injections was defined as the total injections received by participants during the respective safety evaluation period.
TEAE Rates Per Participant Year
时间窗: Approximately up to 54 months
The TEAE rate per participant year was calculated as the total number of TEAE/ participant years. Participant years was defined as the sum of the time (in years) that participant were exposed to study treatment during the respective safety evaluation period.
