TABLE 3.
Results of linear regression analyses between musical activity and GMV in regions-of-interest.
| Dependent variable | Independent variable | B | SE B | Beta | P-value | Total R2 (adj.) | |
| 1 | Frontal GMV | Musical Activity | –0.046 | 0.204 | –0.020 | 0.822 | 0.120 (0.052) |
| 2 | Temporal GMV | Musical Activity | –0.053 | 0.142 | –0.032 | 0.711 | 0.123 (0.055) |
| 3 | Hpc GMV | Musical Activity | –0.007 | 0.012 | –0.052 | 0.551 | 0.102 (0.032) |
| 4 | Cortical GMV | Musical Activity | –0.303 | 0.850 | –0.031 | 0.722 | 0.132 (0.065) |
Models adjusted for scanner site. Musical activity was included as binary predictor, dummy coded with musical activity = 1, no musical activity = 0. Regional GMV was adjusted by total intracranial volume (TIV). B, unstandardized coefficient; Hpc, Hippocampus; SE, standard error; Beta, standardized coefficient; R2, explained variance; GMV, gray matter volume.
