Results from the mediation regression analysis examining the relationship between cultural values of individualism–collectivism, the serotonin transporter gene and affective disorders across nations. All available published data for each variable were included in the regression analyses. Different numbers of included cases in each analysis reflect differences in the amount of available published data (e.g. number of nations) for each variable of interest. β, Standardized beta coefficients. Bold values indicate significant variables.
