+# METHODOLOGICAL INFORMATION 
+ 
+## Environmental/experimental conditions: 
+Cohort study
+ 
+## Description of sources and methods used to collect and generate data: 
+Data were collected from medical records and follow-up at one and three years
+ 
+## Methods for processing the data: 
+*CardioReport has generated the initial database.
+*A code was used for each patient consisting of the first letter of the surname and first name, followed by a number. 
+*Follow-up data were collected on Excel by a study site coordinator.
+
+## Quality -assurance procedures performed on the data: 
+*Inclusion criteria, primary and secondary outcomes were monitored by clinical research assistants.
+*In case of inconsistencies, queries were sent to the study site coordinator for confirmation or correction.
+*Before closing the database, outliers were detected by the statistician and queries were sent to the study site coordinator for confirmation or correction.
