* Low-density lipoprotein (LDL) cholesterol level was logistically regressed on individual patient characteristics, including whether they have been prescribed a statin and their primary care physician's practice characteristics. Census tract number and socioeconomic status were included as random effects in the model. The odds ratio represents the probability of LDL cholesterol being >100.
