I'm surprised that the psychosocial intervention was as effective as it was, however I expected the nutrition arm of the trial to fare better. I guess interacting with intelligent and engaging adults as a child really has long-term developmental benefits.

nutrition is a relative concept. Cornmeal and skin milk are not going to produce amazing result by themselves.

The cornmeal and skim milk was provided to the baby's family in order to discourage them from distributing the baby's formula:

"The nutritional intervention (groups 2 and 3) consisted of giving 1 kg of formula containing 66% of daily-recommended energy (calories), protein, and micronutrients provided weekly for 24 months"

The article implies that the families likely split the formula for multiple members, thus diminishing any effect it may have had on the baby's development.
