Events included in the analysis based on event source and availability of clinical information for adjudication
Events included in the randomised comparison are all unrefuted events.
Confirmed HF events are events that have been confirmed by clinical adjudication.
Unrefuted, unconfirmed HF events are study-reported events (including those also RCD-reported) that have inadequate clinical information to confirm or refute the event.
Definite HF from RCD reports are unrefuted, unconfirmed events reported only in RCD that have been RCD adjudicated as definite HF.
