FIGURE 2.

Scatter plot of the multiple regression model including dose, striatal receptor occupancy and PANSS positive score as predictive/independent variables. The dependent variable, striatal volume increase, is depicted on the y-axis, the independent variables on the x-axis. The model significantly predicted striatal volume increase (r² = 0.411, p = 0.026). Only dose was a unique predictor of volume increase when controlling for the other variables (r² = 0.553, p = 0.028). All model coefficients can be seen in Supplementary Table S1.
