Participant Flow

Data of participants diagnosed with non-valvular atrial fibrillation (NVAF) who initiated treatment with warfarin and any of new oral anticoagulants (NOACs) \[dabigatran, rivaroxaban, apixaban\] between 01-January-2013 to 30-June-2018,registered in Health Maintenance Organizations(HMO)of Colombia were observed retrospectively. Data was retrieved from claim database and medical records during approximately 2 months of this study.

Baseline for this study was 6 months prior to the index date. The index date was the date of first prescription with any of the oral anticoagulants (OACs).
