Table 3. Multivariate logistic regression analyses of the odds ratio (OR) with 95% confidence intervals (95% CIs) between somatic comorbidity (CCI⩾1), education, and cohabitation status among cancer survivors (n=218 003) and the non-cancer population (n=3 313 351) aged 30–90 years, living in Denmark on 1 January 2011, adjusted for sex and age.
