From: Educational quality may be a closer correlate of cardiometabolic health than educational attainment

Associations between educational quality and BMI in the HCP-A data set. The blue line is the association between educational quality and the outcome adjusting for demographics (age, sex, ethnoracial category). The purple line further adjusts for educational attainment as measured by educational attainment. The yellow line further adjusts for fluid IQ. The strength of the association between educational quality and outcomes is virtually unchanged after adjustment for demographics, educational attainment, or fluid IQ.
