A simplified version of the Charlson Comorbidity Index (CCI) was calculated on a scale from 0 to 8, as indicated in24 for an assessment of the individual disease severity. We introduced the CCI factor with two levels (mild for CCI \u003c 3 and severe for CCI ≥ 3), and we tested its differences between gender and age groups by a chi-squared test."}
