Distribution of height-for-age z-scores (HAZ) at up to 5 years of age presented as scatter plot with locally weighted regression smoothing (lowess). 1. Blue indicates those who were in the intervention arm and red those in the control arm (markers for each individual value and line indicating the smoothed regression lines). 2. The black dashed horizontal line represents the mean in the WHO growth standard reference population (HAZ = 0). 3. Those below the lower red dotted horizontal line were stunted (HAZ<−2)
