The overall linear blended mannequin (MIXED) was used to estimate the consequences of supplementation on WISC-III IQ and index scores, Raven’s CPM rating, and faculty efficiency to consider the clustering of youngsters inside colleges. Two dummy variables, representing iron and zinc supplementation, and their interplay time period had been included within the MIXED fashions. As was executed within the unique trial, we examined interactions between iron and zinc on all end result variables.


No variations in anemia prevalence (vary: 11–17%) or top at follow-up had been noticed throughout teams; lastly, neither anemia prevalence nor top at follow-up influenced the leads to Desk 4 (information not proven).
