Orthostatic change variables represent standing value minus supine value. Correlations were adjusted for age, sex, height, body mass index, total cholesterol, high density lipoprotein cholesterol, triglycerides, fasting glucose, hemoglobin A1c, current smoking, use of medication to treat hypertension or dyslipidemia, and prevalent diabetes or cardiovascular disease.
