*Cognitive test scores adjusted for MHVS.

†Other covariates = HADS score, duration of diabetes, A1C, total cholesterol, BMI, hypertension, smoking, alcohol intake, myocardial infarction, angina, stroke, ABI, and level of education.

‡Interactions between plasma cortisol and covariates were tested for all models. Significant interactions were included in the LNS model (cortisol by ABI: β = 0.572, P = 0.002; cortisol by alcohol intake: β = −0.436, P = 0.001) and the g model (cortisol by ABI: β = 0.331, P = 0.038).

§Standardized β. NSI, no significant interactions.
