Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the combined risks of severe bleedings and thrombosis of oral anticoagulation versus no anticoagulation in haemodialysis patients with atrial fibrillation;Secondary Objective: To compare oral anticoagulation to no anticoagulation in haemodialysis patients with atrial fibrillation, regarding the risk of thrombosis and morbi-mortality;Primary end point(s): Combined endpoint: Incidence of severe non-fatal (type 3a, 3b, 3c in the classification from the Bleeding Academic Research Consortium) (Mehran 2011) and fatal bleedings (type 5) plus Incidence of non-fatal and fatal strokes according to the therapeutic strategy, during 24 months.;Timepoint(s) of evaluation of this end point: During 24 months | — |
Secondary
| Measure | Time frame |
