Note. Standardized (ß) and unstandardized (b) estimates are displayed. Estimates are from adjusted models that include the following covariates: age, sex, race, BMI, smoking status, time between the baseline visit and the blood draw, and total number of comorbidities at baseline. Results that are p <.05 are in bold face.
