Non-parametric partial correlation between fornix FD and RAVLT-DelayedR changes. Non-parametric partial correlation, controlling for age (at the start of the intervention), site and gender revealed a significant correlation between fornix FD change and change in RAVLT-DelayedR performance (measuring episodic (long-term) verbal memory). For visualization, the residuals of multiple regression are plotted and a linear regression line was chosen to depict the positive correlation. T0, baseline measurement; T1, 6 months measurement.
