In the above table, covariates include education, gender, age, depression, waist circumference, triglycerides, HDL, fasting blood glucose, smoking, and kilocalories. Main effects for the two variables of interest, APOE ε4 status and SBP, can be found above. The interaction result is represented by the final variable in the table.
