HDDS: Household Dietary Diversity Score; FCS: Food Consumption Score.
^ǂIncremental costs represent the difference between total costs for LIG and other support programs.
^¥Comparator households represent MDM beneficiaries participating in other support programs but not the LIG program. For the purposes of comparative analysis, it was assumed that 1,330 comparator households were participating in the other support programs, to match the number of LIG participant households.
†Incremental costs were estimated from a societal perspective.
