Demographics of BDNF genotype groups
| Met carriers (n = 16) | Val/Val carriers (n = 16) | p* | |
|---|---|---|---|
| Age (years) | 26.9 ± 8.5 (20–49) | 26.5 ± 8.1 (19–49) | 0.91 |
| Education (years) | 16.6 ± 2.2 (14–21) | 16.2 ± 2.8 (10–21) | 0.31 |
| Right-handedness (%) | 92.5 ± 9.3 (80–100) | 95.6 ± 6.3 (80–100) | 0.31 |
| BDI | 3.6 ± 4.8 (0–15) | 3.9 ± 4.8 (0–18) | 0.91 |
Data expressed as mean ± SD and [range (minimum to maximum)]. Note that genotype groups did not differ with regard to age, education, handedness, and scores on the Beck's Depression Index (BDI). Handedness score were determined according to the Edinburgh Handedness Inventory.
