N; number of children enrolled in the study, n; number of malnourished children, CI; confidence interval, NA; not applicable, WAZ; Weight-for-Age Z-score, HAZ; Height-for-age Z-score, BAZ; BMI-for-Age Z-score
*; The WHO reference data for WAZ used by the WHO AnthroPlus software were for age ≤ 10 years, therefore underweight was estimated for children aged 5–10 years (n = 231)
