  1. Each hospital is considered a silo. Categorical columns have the number of categories (C) and the percentage of the most frequent (%). Continuous variables have a mean (\(\mu\)) and standard deviation (\(\sigma\)). Abbreviation meaning in the “Appendix”. The first row is the number of patients. Bold rows were used as target (n = 19).
