Fig. 1From: Motor development related to duration of exclusive breastfeeding, B vitamin status and B12 supplementation in infants with a birth weight between 2000-3000 g, results from a randomized intervention trial a. Dose-response relationship of cobalamin, folate, PLP, riboflavin, tHcy and MMA at 6 months with months of exclusive breastfeeding by Generalized additive models (GAM), adjusted for gender, infant weight at 6 months and iron and folate supplementation. The solid line shows the fitted model and the shaded areas indicate 95 % CIs. PLP, pyridoxal 5´phosphate; tHcy, total homocysteine; MMA, methylmalonic acid. b. Dose-response relationship of tHcy and MMA at 6 months with AIMS scores at 6 months by Generalized Additive Models (GAM), adjusted for gender, infant weight at 6 months and iron and folate supplementation. The solid line shows the fitted model and the shaded areas indicate 95 % CIs. tHcy, total homocysteine; MMA, methylmalonic acidBack to article page
