  1. 1Values are mean ± SD of velocity Z-scores based on WHO standard. LVZ, length velocity Z-score; P1, Period-1; P2, Period-2; WVZ, weight velocity Z-score.
  2. 2Student test P values for group comparisons a 5% significance level.
  3. 3Children received breast milk in addition to other solids and liquids.
