  1. Significance level: ***, ** and * is at 1% , 5% and 10% respectively; and Std. Errors ( in parenthesis) are adjusted for each clusters in ea_id (enumeration areas or primary sampling units). Under each malnutrition indicators, in the contribution column, the figure in parenthesis represents the percentage contribution. Each figure is rounded to two digits only. Hence, point zero zero doesn't mean that it is actually zero, it is rather rounded value
