  1. Age and Gender have been controlled in all models
  2. All models had random intercepts
  3. All time-dependent covariates had a fixed slope
  4. T1: at discharge; T2: 30 days; T3: 90 days; T4: 180 days
  5. Beta: non-standardized regression coefficient in multilevel analyses; SE: standard error
