Note:—Dependent variable is proportion of activated voxels in hippocampal region of interest.
LH indicates left hippocampal activation; LHV/ICA, left hippocampal volume divided by single-section intracranial volume; RH, right hippocampal activation; RHV/ICA, right hippocampal volume divided by single-section intracranial volume; Group X LHV/ICA and Group X RHV/ICA, interaction term between group and hippocampal volume. Significant values of P are indicated in boldface type.
* Group term becomes nonsignificant (P = .314) when the interaction term, Group X RHV/ICA, is removed from the ANCOVA model.
