Excluding 58 patients with incomplete 3 months follow-up information and no reported predefined clinical endpoint (recurrent ischaemic stroke, systemic embolism, myocardial infarction, haemorrhagic stroke, major bleed or all-cause death) within 3 months (‘drop-outs’), the ‘follow-up cohort’ included 650 patients. The p value is given for the comparison of the follow-up cohort and the drop-outs.
