Scatter plots to show the relationship between infant cognitive scores and maternal plasma choline metabolites.

<p>Plasma metabolite concentrations were normalized by a single natural log transformation (A, B and C). Infant cognitive development was assessed using the Bayley Scales of Infant Development III. The antilog of the natural log is equivalent to the exponential of the natural log value, that is 2.718 to the exponential of the value plotted on the x axis or e^x. The results were analysed for 154 mother-infant pairs using Pearson correlation analysis, A. choline r = 0.190, p = 0.019, B. betaine r = 0.288, p = 0.0003, C. dimethylglycine, r = 0.157, p = 0.053.
