Fig. A. Scatterplot showing the association between age and methylation of SLC6A4. There was a positive correlation between both variables indicating that older age is associated with higher levels of methylation. Table A. Parameters of the investigated regression model, including sex, age, MDD diagnosis, childhood trauma, and hippocampal volume as independent variables, and SLC6A4 methylation (CpG 5&6) as outcome variable. Table B. Parameters of the investigated regression model, including sex, age, MDD diagnosis, childhood trauma, and hippocampal volume as independent variables, and SLC6A4 methylation (CpG 11&12) as outcome variable. Table C. Parameters of the investigated regression model, including sex, age, MDD diagnosis, childhood trauma, and hippocampal volume of CA2/3 as independent variables, and SLC6A4 methylation as outcome variable. Table D. Parameters of the investigated regression model, including sex, age, MDD diagnosis, childhood trauma, and hippocampal volume (CA4/DG) as independent variables, and SLC6A4 methylation as outcome variable. Table E. Parameters of the investigated regression model, including sex, age, MDD diagnosis, childhood trauma, and hippocampal volume (CA1) as independent variables, and SLC6A4 methylation as outcome variable.
