Identified interactions across main models and sensitivity analyses
| Outcomes | Models | Interaction effects | Type of analysis |
|---|---|---|---|
| Days not at home (count specification) | Generalized Poisson regression tree | Baseline Zarit Burden score (≤ 28, > 28) | Primary |
| Random forest with interactions | Baseline Zarit Burden score, CESD-10, nosos score and patient age | Sensitivity | |
| Proportion of days not at home | mCART regression tree | None | Sensitivity |
| Any days not at home | Generalized linear regression tree (binomial) | None | Sensitivity |
| mCART classification tree | None | Sensitivity | |
| CESD-10 score 12-month follow-up | Linear regression tree | Baseline CESD-10 score (≤ 8, > 8) | Primary |
| mCART regression | None | Sensitivity | |
| Random forest with interactions | Baseline CESD-10 score and, Zarit Burden score | Sensitivity |
