| Hemisphere (L/R) | 7/8 | 9/10 | 16/18 | 15/5 | 12/8 | 27/13 | 0.076 | 0.433 | – |
Values are represented as mean ± SD, unless otherwise specified. Data was analysed using a two-way ANOVA including diagnosis and sex as relevant factors. Sex, suicide and hemisphere were analysed using a chi-square test.
