Reproduction of direct mathematical dependencies. In (a), the error in passing time between the child’s age and the study time is shown. It is calculated between any two successive visits, where \(\Delta _{alter }\) is the time passed for the child, and \(\Delta _{time }\) is the time passed for the study. In (b), the error in reconstructing a direct mathematical relationship within a single visit is shown, i.e., the sum of proteins (EW_p), fats (Fett_p) and carbohydrates (KH_p). A perfect reconstruction of the three variables should always sum to 100.
