Model fit for multi-level logistic regressions for the separate predictive factors, for the number of predictive factors and for all three predictive indicators simultaneously analysed
| Predictive factor | Model fit by Akaike’s index AIC1 |
|---|---|
| Many previous episodes |
222.5 |
| Long duration |
230.1 |
| Definitely better by the 4th visit |
236.6 |
| Number of predictive factors (0–3) |
226.6 |
| Long duration, Many previous episodes, Definitely better by the 4th visit. | 225.4 |
1 A smaller value for AIC indicates better fit to data.
