*
Numbers of participants and deaths included in the analysis, including those in the middle tertile.
†
Adjusted for age and sex.
‡
Adjusted for all covariates (age, sex, socioeconomic status, body mass index, health behaviours and chronic disease).
§
Adjusted for all covariates and other inflammatory biomarkers.
¶
Four participants with unknown cause of death were excluded from these analyses.
