| Adu‐Afarwuah et al. (2007) | Ghana | 6 months | % of children able to walk independently by 12 months of age | Fortified spread | 98 | 49%* |
| No intervention | 96 | 25% | ||||

| Oelofse et al. (2003) | South Africa | 6 months | Denver Development Screening Test score | Fortified food | 16 | 83.0 ± 10.9 |
| No intervention | 14 | 88.2 ± 9.0 | ||||

| Beckett et al. (2000) | Indonesia | 12 and 18 months | Mean (±SD) slope for Bayley mental ANCOVA models | High energy + micronutrients | 11 | 6.13 ± 0.98*, † |
| Low energy + micronutrients | 12 | 4.68 ± 1.41 † | ||||
| Diff: +31.0% | ||||||
Diff, difference; PP, percentage point; ANCOVA, analysis of co‐variance. *Means are significantly different (P < 0.05). †Values are slopes for children 18 months of age at baseline with LAZ lower than the median for the cohort‐treatment groups, because of a significant cohort × length category × treatment interaction (P = 0.008).
