CCI Charlson modified comorbidity index. Continuous variables are given as mean ± SD, when normally distributed, or as median (IQR), when skewed. P-values between the four groups are calculated based on parametric (ANOVA)p , nonparametric (Kruskall Wallis)np, or Chi-squared2 statistics. Note: Numbers of complete data are given in parentheses for each variable.
