Sex differences in the associations between occupational attainment, cognition and APOE4 genotype in mid-life. (A) A trend effect interaction is shown between sex and occupational attainment on episodic and relational memory. (B) A significant interaction is shown between sex and occupational attainment on episodic and relational memory in APOE4 carriers. (C) APOE4 non-carriers showed no significant interactions between sex and occupational attainment. On the x axis, higher scores represent greater occupational attainment, and on the y axis, higher scores represent better episodic and relational memory
