Fig. 6.

This diagram shows the results from the mediation analysis for Picture Sequence Memory test. The independent variable was the chronological age of the TLE patients. The mediator was either their functional or structural brain age. Functional age partially mediated (P < 0.001) the association between chronological age and the test score (top triangle), whereas structural age did not (bottom triangle). Numbers in parentheses are results after the mediator was introduced.
