Supplementary Figure 4: Mendelian randomization test for a putative causal effect of depression (n = 629,934 individuals; 56 instrumental variables) on neuroticism (n = 29,496 twin pairs) using inverse weighted regression, MR Egger and a weighted median test.

Center values reflect the effect of each instrumental variable on each trait with the respective error bars reflecting the standard error of the variable’s effect on each trait.
