^*It was decided a priori to analyse the adjusted odds of in-hospital cardiopulmonary and renal complications as a composite outcome to improve power.

^†Includes acute coronary syndrome, heart failure, ventricular arrhythmia, or cardiac arrest.

^‡Number of events was too low to allow for fully adjusted regression modelling.

^§Post hoc analysis; includes transient ischaemic attack and ischaemic or haemorrhagic stroke.
