Growth and nutritional status
MUAC-Z
The specific hypotheses regarding growth and nutritional status are as follows:Mean LAZ, WAZ, WLZ, and MUAC-Z measured at 15, 18, 21, and 24 months after village enrollment are higher among 6–8- and 12–14-month-old children in villages that receive two-dose AZI regimen than among same-aged children in villages that receive placebo.Mean LAZ, WAZ, WLZ, and MUAC-Z measured at 15, 18, 21, and 24 months after village enrollment are higher in 6–8- and 12–14-month-old infants in villages that receive four-dose AZI regimen than among same-aged children in villages that receive placebo.Proportion of children with LAZ, WAZ, WLZ, or MUAC-Z below − 2 at 15, 18, 21, and 24 months after village enrollment is higher in 6–8- and 12–14-month-old infants in villages that receive two-dose AZI regimen than among same-aged children in villages that receive placebo.Proportion of children with LAZ, WAZ, WLZ, or MUAC-Z below − 2 at 15, 18, 21, and 24 months after village enrollment is higher in 6–8- and 12–14-month-old infants in villages that receive four-dose AZI regimen than among same-aged children in villages that receive placebo.
