The models were used to estimate the absolute risk of both outcomes according to CCIS groups across ages 40-85 for both sexes. The estimated absolute risks of severe COVID-19 and death were increased for CCIS 1-2, 3-4, and > 4 compared with those for CCIS 0 across ages and sexes (Fig. 1) . A Charlson Comorbidity Index Score above 0 was associated with an increased risk of severe COVID-19 and death when controlled for age and sex.
