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.
