Effect of complementary food supplementation on the prevalence of MDD by interview age in children participating in a randomized controlled supplementation trial in rural Bangladesh (n = 5396)1
| CFC only | Chickpea | Plumpy'doz | Rice and lentil | WSB++ | |

| 9 | 29.1 | 35.1 | 30.6 | 31.8 | 32.1 |

| Difference (95% CI)2 | — | 4.1 (0.7, 7.5)** | 4.0 (1.2, 6.9)*** | 2.6 (−0.7, 6.0) | 4.2 (0.9, 7.5)** |
Complementary food supplements were not included in the calculation of the MDD. Plumpy'doz is manufactured by Nutriset. CFC, child feeding counseling; MDD, minimum dietary diversity; WSB++, fortified wheat-soy blend.
Predicted marginal differences across all ages, P values, and 95% CIs were determined with the use of a mixed-effects logistic regression model with MDD as the dependent variable and age, supplementation group, and age × supplementation group interaction terms as independent variables with random intercepts for the child and sector. ** P > 0.01 but ≤ 0.05, ***P ≤ 0.01.
