The WAZ, HAZ and BAZ growth trajectories in 2016, 2018 and 2020 (Note: WAZ- weight-for-age z-score, HAZ- height/length-for-age z-score, BAZ- BMI-for-age z-score; shaded areas imply 95% CIs; the horizontal dashed lines represent the WHO standard median level, the vertical dashed line represent respectively the age of 12 and 24 months; the Epanechnikov kernel-density function was used in local polynomial regressions and the rule-of-thumb technique were used to select the bandwidth.)
