Data are OR of high levels of inflammatory marker (95% CI). For risk of high inflammation level associated with diabetes and hyperglycemic status, model 1 is adjusted on age, sex, race, smoking status, alcohol intake, education, and site. Model 2 adds total body fat, visceral fat, and height. Model 3 adds cardiovascular diseases, hypertension, peripheral arterial disease, renal insufficiency, arthritis, pulmonary disease, anti-inflammatory, statin, and estrogen use. For relationship between glycemic control and inflammation in diabetes, models 1 and 2 are the same and model 3 adds diabetes duration.
