Independent Risk Factors for Discontinuing Statin Therapy, From Logistic Regression Analysis* S. Schneeweiss, et al. Circulation 2007;115: CHF indicates congestive heart failure. *Each factor was adjusted for all other factors and represents independent effect estimates. The effects of patient risk factors are therefore independent of the policy effects in this analysis. †The 100% coinsurance policy affected a fair proportion of elderly beneficiaries because the policy required deductible payments that were based on income. Before this deductible was reached, patients had to pay 100% of costs out of pocket.
