  • Patients in the extreme quartiles were included as affected individuals if they met the criteria for the examined manifestation; otherwise as censored individuals.

  • Values in bold indicate p<0.05.

  • *The mean age at the event includes only affected individuals.

  • †The mean survival is defined as the age at which 50% of individuals in each quartile are affected by the examined event.

  • ‡Unadjusted.

  • AE, arterial event (myocardial infarction or ischaemic cerebrovascular disease); CVE, cardiovascular event (AE or VTE); ESRD, end-stage renal disease; GRS, genetic risk score; SDI, SLICC Damage Index29 ; VTE, venous thromboembolic event (deep vein thrombosis or pulmonary embolism).
