  1. 1 values are mean ± SD
  2. a Undjusted p values are group x time of assessment interaction and were obtained by repeated measures ANOVA analysis. Experimental group, MNP and NMS; Control group, NMS only. WAZ Weight-for-age z score, LAZ Length-for-age z score, and WLZ Weight-for-length z score
  3. Difference between groups at same time point is significant (at the 0.05 level) when letters are same
  4. * Significantly different by paired t-test between baseline and selected time-point in the same intervention group at the 0.05 level
  5. ** Significantly different by paired t-test between baseline and selected time-point in the same intervention group at the 0.001 level
  6. Significantly different by paired t test between month 12 and 15 in the same intervention group at the 0.05 level
  7. 2 p value after adjusting for sex (Model 1) at 12 months, groups were compared using one-way ANCOVA
