Multivariate linear regression model (n = 58)
| Dependent variable | Explanatory variable | β |
|---|---|---|

| * = p<0.05; ** = p<0.01; *** = p<0.001, **** = p<0.0001. | ||
| CLTR, consistent long term retrieval; DR, delayed recall; LTS, long term storage; MTR, magnetisation transfer ratio; NAWM, normal appearing white matter; PASAT, paced auditory serial addition test; SDMT, symbol digit modalities test; SRT, selective reminding test; 10/36-DR, spatial recall test evaluating long term visuospatial memory. | ||
