  1. aCategorical variables were summarized as number (percent), continuous variables summarized as median (25–75th percentile
  2. bFor DHAKA Study, age is presented in months; for the NIRUDAK Study, age is presented in years
  3. cNutritional status was calculated using the mid-upper arm circumference (MUAC) as outlined in the literature (26–28). For the DHAKA study, the proportion of children with undernutrition was determined using a MUAC < 115 mm for severe wasting and 115–125 mm for moderate wasting and > 125 for normal. For the NIRUDAK Study, patients between the ages of 5–9 years old were categorized as severe wasting if MUAC was < 135 mm, moderate wasting if MUAC was 135–145 mm and normal if MUAC measurement was > 145 mm. Patients between the ages of 10–14 years old were categorized as severe wasting if MUAC measurement was < 160 mm, moderate wasting if MUAC measurement was 160–185 mm and normal if MUAC was > 185 mm. For patients 15 years of age and older, severe wasting was defined as a MUAC measurement < 185 mm; moderate wasting was categorized as a MUAC 185–210 mm; normal was defined as a MUAC measurement > 210 mm
