Major bleeding is defined as i) overt and associated with a fall in the haemoglobin level 2 g/dl or more, ii) leads to transfusion of 2 units or more, iii) is retroperitoneal, iv) occurs into a major prosthetic joint, or v) in intracranial. Minor bleeding is defined as overt bleeding that does not meet the criteria of major bleeding.
