*Cox model, matched for age, sex and geographical region.
†Cox model additionally adjusted for history of cancer, heart failure, ischaemic heart disease, infections, lung disease, kidney failure, stroke, joint surgery, venous thromboembolism, region of domicile, education, civil status, country of birth and time hospitalised in days (previous 10 years, and previous 1 year).
‡Note that follow-up in this table ends 18 August, which is why numbers and HRs differ slightly compared with all other analyses of all-cause mortality in which follow-up ends 1 September.
