*SAM cases 6–60 months are those that met WHO criteria (matched and missed cases). For infants aged <6 months, the WHO criteria are less specific but 31 in this age group preintervention and 48 postintervention had anthropometric and/or oedema data and their data are included.
†Two-sample t-test was performed.
‡Χ2 test was performed.
SAM, severe acute malnutrition.
