  1. * n, denotes number; IQR, denotes interquartile range
  2. ¶ haemorrhagic tendency was present when at least one of the following was present: a) positive tourniquet test, b) petechiae, ecchymoses or purpura, c) bleeding from the mucosa, gastrointestinal tract, injection sites or other locations, d) haematemesis or melena
  3. £ spontaneous haemorrhage was defined as all haemorrhagic manifestations not caused by a tourniquet test or venapuncture
  4. † hypotension is defined to be a systolic pressure of <80 mmHg for those <5 years of age, or <90 mmHg for those ≥ 5 years [2]
  5. ‡ the presence of pleural effusion was assessed through a chest X-ray
