Results of the economic analysis for both cost per point change in CDI-2 and cost per QALY
| Outcome | Analysis | Incremental cost | CI | Incremental effect | CI | ICER |
| CDI-2 difference | Complete case | 334 | (−606, 1274) | −4.6 | (−10.1, 0.87) | 73* |
| Imputed | 292 | (−558, 1142) | −4.8 | (−10.3, 0.75) | 61* | |
| QALY difference | Complete case | 355 | (−596, 1305) | −0.0027 | (−0.04, 0.03) | Negative |
| Imputed | 286 | (−1063, 1634) | 0.0019 | (−0.063, 0.067) | £152 822 |
*For ICERs related to change in CDI-2, the sign of the difference has been changed as a negative change in CDI-2 represents an improvement.
CDI-2, Children’s Depression Inventory-2; ICER, incremental cost-effectiveness ratio; QALY, quality-adjusted life year.
