Outcome parameters
ADVERSE EVENTS, EVENT
The primary outcome parameter was successful EVT treatment, defined as closure of the defect primarily by EVT. Closure was confirmed by endoscopic inspection and/or CT imaging. Therapy was considered unsuccessful if the defect persisted or increased under EVT or if adequate vacuum therapy was not achieved.
Secondary outcome parameters included additional treatment modalities, adverse events (AEs), and combined in-hospital and 30-day mortality. AEs were defined as any event interfering with the scheduled treatment and were classified by degree of consequences
