  2. aCategorical variables (sex, number of Hs, coverage of hospitalization costs, type of admission, and number of deaths) are described as absolute frequencies/total number of cases in the row (percentages), and quantitative variables are described as (number of valid cases) mean and standard deviation (age) or median and interquartile range (all other variables).
  3. bOdds ratio (OR) and 95% confidence interval (95% IC) of the univariate binary logistic regression model.
  4. cWald test p value, results < 0.05 indicate statistical significance.
