| Outcome | Sample size | Effect size (95% CI) | Quality | Interpretation of effecta |
|---|---|---|---|---|
| Attention problems score at approx. 2 years follow up (Attention Problems Scale in the preschool Child Behaviour Checklist) | 111 | MD −0.90 (−1.66 to −0.14) | Very Low | Effect favours intervention group, but it may be less than the MID |
| Cognitive flexibility score at approx. 2 years follow up (Dimensional Change Card Sort task for pre-schoolers) | 111 | MD 5.13 (0.51 to 9.75) | Very Low | Effect favours intervention group, but it may be less than the MID |
| Receptive vocabulary assessed at approx. 36, 48, and 60 months of age for a composite score (Peabody Picture Vocabulary Test (PPVT third edition). | 88 | MD 7.10 (0.32 to 13.88) | Very Low | Effect favours intervention group, but it may be less than the MID |
No meaningful difference: crosses line of no effect but not line of MID; Could not differentiate: crosses line of no effect and line of MID; May favour: confidence intervals do not cross line of no effect but cross MID; Favours: confidence intervals do not cross line of no effect or MID
