Multiple regression model with ¹¹C-Tyr cerebral protein incorporation as outcome variable, using baseline plasma Phe, Phe tolerance, age, k_1,2 and k_2,1 as predictor variables. Only statistically significant predictor variables are shown. k_2,1: ¹¹C-Tyr transport from blood to brain. SE: standard error.
