HAZ = height-for-age Z-score; MUAC = mid-upper arm circumference; WAZ = weight-for-age Z-score; WHZ = weight-for-height Z-score; all models adjusted for the child’s age in months, gender, and study arm with standard errors adjusted for clustering at the community level and an interaction term for malaria parasitemia by the community treatment arm.
