Abbreviations: BP, blood pressure; COPD, chronic obstructive pulmonary disease; HbA1c, hemoglobin A1c; LDL-C, low-density lipoprotein cholesterol; MA, Medicare Advantage; MI, myocardial infarction.
SI conversion factors: To convert HbA1c to a proportion of total Hb, multiply by 0.01; LDL-C to millimoles per liter, multiply by 0.0259.
