Performance of SVR models (R2 statistic) predicting cognitive composite measures.
| Dataset | Cognitive Composite | SVR R2 (Uncorrected) | SVR R2 (Partial Age) | SVR R2 (Partial CVH) |
|---|---|---|---|---|
| Resting-State fMRI | Global | .045** | <.001 | .005 |
| Episodic Memory | .007 | .018 | .021 | |
| Attentional Control | .106*** | .002 | .007 | |
| Attentional Control (Corrected for Trails A) | .020^ | <.001 | <.001 | |
| Task-Driven fMRI | Global | .025 | .024 | .002 |
| Episodic Memory | .156 | .133 | .178 | |
| Attentional Control | .135** | .141** | .062* | |
| Attentional Control (Corrected for Trails A) | .141** | .139** | .093* |
Performance is presented for uncorrected models, as well as after statistically controlling for age and cardiovascular health (CVH) variables as covariates in BOLD SD estimates.
