2.4 Data extraction
A standardized data collection form was used to obtain the following
data from each study including name of the first author, year of
publication, country of the study, study population, main inclusion and
exclusion criteria, demographic data of participants, ablation procedure
details, AAD therapy, endpoint for recurrence, recurrent rates, and
reported adverse event.
To ensure accuracy, this data extraction process was independently
performed by all investigators. Any data discrepancy was also resolved
by referring back to the original articles.
