Trajectory of weight gain with and without treatment with psychostimulants. Estimated trajectory of BMI z score change over a two-year period in a hypothetical participant on risperidone monotherapy and one on a combination of risperidone and a psychostimulant. These trajectories were modeled for a prototypical participant using the sample mean for baseline BMI z score (0.13), age at the onset of risperidone treatment (9.3 years), daily weight-adjusted dose of risperidone (0.03 mg/kg/d) and methylphenidate (0.9 mg/kg/d).
