Association between working memory performance and energy-adjusted total choline intake across four levels of Phe concentration (120 µmol/L, 360 µmol/L, 600 µmol/L, 800 µmol/L) in a subsample of PKU participants with historical Phe data (n = 30). Data points represent observed data adjusted for intellectual ability (matrix reasoning) and IDC from 6 to 11 years
