  1. IG: intervention group; CG: control group; RR: relative risk of the occurrence of at least one admission; CI: Confidence interval.
  2. The data are expressed as frequency (percentage) for categorical variables, and as mean and standard deviation (SD) and median and interquartile range (IQR) for continuous variables, unless otherwise stated.
  3. I Chi-square or Fisher’s exact tests were used to compare categorical variables and Student’s t-tests or non-parametric Wilcoxon tests to compare continuous variables at each time point.
  4. IIAdmissions to hospital for respiratory and heart-related problems.
  5. III Mean length of stay per admission (hospitalisation), considering only patients who were admitted at least once (12 in the IG and 19 in the CG).
