OR, odds ratio; CI, confidence interval; AIC, Akaike's information criterion.

Significant association. The effect of age was modelled per 1-year increase. Male is compared with female. Model 1 (risk of symptomatic illness): R²_U=0.011, AICc=928; Model 2 (risk of severe disease): R²_U=0.146, AICc=304; Model 3 (risk of death): R²_U=0.152, AICc=117.
