Tyrosine Is Associated with Insulin Resistance in Longitudinal Metabolomic Profiling of Obese Children
Table 1
Characteristics of participating children at start and end point of the 1-year intervention period. Characteristics are shown for all obese children (), children with substantial weight loss (WL, ), and children without substantial weight loss (nWL, ) as mean ± SD unless stated otherwise.
