Abbreviations: CI=confidence interval; HR=hazard ratio.

Model 1 is unadjusted.

Model 2 is adjusted for age and sex.

Model 3 is adjusted for age, sex, body mass index (continuous), type of cancer, time since cancer diagnosis (continuous), smoking status, healthy eating index, weekly drinking, hypertension, diabetes, asthma, arthritis, myocardial infarction, stroke, congestive heart failure, hospitalisation in the prior year, self-reported health status, weekly walking (ordinal), haemoglobin, albumin, and C-reactive protein.
