  1. Linear regressions showed that changes in BAARS hyperactivity/impulsivity and total scores under a single dose of MPH were significantly associated with improvement in corresponding scores after two-month treatment (follow-up). The former survived correction for multiple comparisons. Symptom improvement at follow-up can be calculated according to the formula Y = α + βX, where α and β are the constant and regression coefficient, and X the acute change of interest. Statistically significant results are displayed in bold.
