We used calendar year as the time scale, with survivors having a censoring date of 31 December 2017 (person years follow-up = 13,814) for all-cause mortality and with survivors having a censoring date of 31 December 2015 (person years follow-up = 12,180) for cause-specific mortality

^a Indicates non-cardiovascular disease and non-cancer mortality

^b Adjusted for age, country of birth, and living arrangement
