From: Total choline intake and working memory performance in adults with phenylketonuria
Interaction of choline consumption (low and high) and study group (non-PKU and PKU) based on ANCOVA for overall working memory performance (reflected by composite measure). Low and high choline consumption represent intake below and above the sex- and age-specific population averages, respectively. Estimated marginal means and 95% confidence intervals are reported for each group. This analysis did not identify choline consumption as a significant effect modifier (p = 0.36). Abbreviations: HC, high choline; LC, low choline
