Median values within a row with unlike superscript letters are statistically significantly different. Row letters compare both yellow and white cassava groups during and after the intervention.
Calculated from post-intervention data at time point 2 based on the assumption that yellow cassava foods replaced all white cassava foods for all children.
Low energy intake is defined as energy intake less than IOM’s recommended age-specific requirement.
