  1. β: coefficient of parameter. CI: confidence interval. *: p-value < 0.05. **: p-value< 0.01. ***: p-value < 0.001. ref.: reference category
  2. Note: The DHS categorises the wealth index as poorest, poor, middle, richer and richest. However, in this work, we combined poorest and poorer as poor. Also, middle, richer and richest were combined as average/rich. Similar recoding was done for size at birth, place of delivery and maternal education
