Fig. 2. (A) Comparison of mean height of the children who received vitamin A supplementation for six months (96.3 cm) with the height of those who were not supplemented with the vitamin (94.9 cm). The height increase was 1.4±0.42 cm greater for the vitamin A supplemented children, p<0.002. The pre-treatment adjusted mean was 92.0 cm. The bars represent the mean height increases for the non-vitamin A supplemented compared to the vitamin A supplemented children, e.g. 2.9 cm versus 4.3 cm, respectively. (B) Comparison of mean height-for-age Z score of the children who received vitamin A supplementation with the mean height-for-age Z score of those who were not supplemented with the vitamin, -2.44 vs. -2.11, p<0.001. The pre-treatment adjusted mean was -2.37.
