Relationship between plasma risperidone concentrations and clinical features in chronic schizophrenic patients in China

Figure 1 Comparison of concentrations of plasma risperidone + 9-hydroxyrisperidone/dose and plasma risperidone + 9-hydroxyrisperidone/(dose × kg) between males and females. A: Concentrations of plasma risperidone + 9-hydroxyrisperidone/dose (Student's t-test); B: Concentrations of plasma risperidone + 9-hydroxyrisperidone/(dose × kg) (Mann-Whitney U-test).

Figure 2 Correlation of sum of steady-state trough risperidon + 9-hydroxyrisperidone concentrations in plasma/(dose × kg) with age for 50 patients (Pearson’s correlation coefficient = 0. 436, P < 0.01).
