There was a significant age interaction on the treatment effect.
The age interaction with the predictors was tested without finding any statistical significance or model modifications.
The lateralization-by-age interaction was not significant for movement execution.
As indicated in Table 2, the SES-age interaction terms are not significant (P > 0.1) in the depressive symptom model.
A voxel-wise regression examining the relationship between age and activation revealed a significant group-by-age interaction.
Recent studies have reported several genetic, health, and aging interaction effects in predicting cognitive performance and change.
The Condition × Age interaction (Figs. 1 and 2) indicates that the costs of the IVIS interactions were greater for older adults than for younger adults.
Although age interaction was statistically robust, given the exploratory nature of this finding, results need to be interpreted with caution.
This gender by age interaction appears to underlie the modulation of BRS and autonomic function by sex hormones [32], [33].
In an exploratory step, we also tested for a DTI measure – age interaction and a DTI measure – baseline MADRS interaction effect on remission.
