Figure 2.

Interactive effects with the route learning task. Plots depict a split at 0STD for hippocampal volume and -1STD, 0STD, 1STD for the route learning variable for illustration purposes. Analyses were conducted with continuous variables. Higher RL-Retrieval scores reflect worse performance. A) Hippocampal volume and RL-Retrieval in total sample without an outlier. B) Hippocampal volume and RL-Retrieval in CDR=0 subsample without an outlier. See Supplementary Table 4 for results of the simple slopes analyses.
