infancy on cognitive, motor and language
The primary trial assessed the impact of milk–cereal mix supplementation on linear growth at 12 months in a total of 1548 infants
Trial profile. For 12 months of neurodevelopment assessment, some infants had crossed the window period of +4 weeks at the time they were approached for consenting. For these children, the study team visited the house at the time of anthropometric assessments at 15 months of age and obtained written informed consent for neurodevelopment assessments at 24 months of age.
Baseline characteristics of the children assessed and their families, by the study groupsLAZ, length-for-age z scores; WLZ, weight-for-length z-scores; WAZ, weight-for-age z-scores; IQR, interquartile range.Values are mean and standard deviation unless reported otherwise.Calculated using WHO standards.The findings of the analysis for the effect of supplementation on neurodevelopment outcomes at 12 months of age have been presented in
