Effects of MNP compared with placebo fortification on morbidity measures in preschoolers over time1,2
| Time (T1 vs. T0) | OR (95% CI) | P 3 | |
|---|---|---|---|
| Acute respiratory infection, episodes | MNP | 1.58 (0.7, 3.6) | 0.27 |
| Placebo | 1.15 (1.01, 1.3) | 0.03 | |
| MNP vs. placebo | 1.38 (0.7, 2.9) | 0.39 | |
| Time × MNP | — | 0.944 | |
| Diarrhea, incidents | MNP | 0.82 (0.4, 1.7) | 0.61 |
| Placebo | 0.78 (0.7, 0.9) | 0.003 | |
| MNP vs. placebo | 1.05 (0.5, 2.1) | 0.89 | |
| Time × MNP | — | 0.074 |

Generalized linear mixed-effects regression models with random preschool and subject intercepts fitted for each outcome; Time in months is treated as continuous. MNP, multiple micronutrient powder.
2
Recall by month over 15 d.
3
P value for OR ≠ 1.00.
4
P value for time–MNP interaction effect.
