A Poultry Value Chain Intervention Promoting Diversified Diets Has Limited Impact on Maternal and Child Diet Adequacy during the Lean Season in a Cluster Randomized Controlled Trial.

We found suggestive evidence that synergies between intervention components may have introduced heterogeneity in effects on diet.
