Cost-related nonadherence by medication type among Medicare Part D beneficiaries with diabetes.
Article in Medical care, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02604901 (Effect of Community Pharmacist Intervention on Adherence to Long-Term Medications), which is not on this map. Cited by 28 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundDespite the rollout of Medicare Part D, cost-related nonadherence (CRN) among older adults remains a problem.
objectivesTo examine the rate and correlates of self-reported CRN among a population of older persons with diabetes. RESEARCH
designCross-sectional. SUBJECTS: A total of 1264 Part D patients with diabetes, who entered the coverage gap in 2006. MEASURES: Initial administrative medication lists were verified in computer-assisted telephone interviews, in which participants brought their medication bottles to the phone. Medications were classified into cardiometabolic (diabetes, hypertension, cholesterol-lowering), symptom relief, and "other." Participants were asked if they had any CRN during 2006, and if so to which medication/s. We used the person-medication dyad as the unit of analysis, and tested a multivariate random effects logistic regression model to analyze the correlates of CRN.
resultsApproximately 16% of participants reported CRN. CRN was more frequent for cholesterol-lowering medications (relative risk, 1.54; 95% confidence interval, 1.01-2.32) compared with medications taken for symptom relief. CRN was reported less frequently with increasing age above 75 years, compared with patients between 65 and 69. In addition, compared with those with incomes of ≥$40,000, CRN risk for those with incomes of <$25,000 was markedly higher (relative risk, 3.05; 95% confidence interval, 1.99-4.65).
conclusionsIn summary, we found high rates of CRN among Medicare beneficiaries with diabetes, particularly those with lower incomes. We observed more frequent CRN for cholesterol-lowering medications as compared with medications for symptom relief. Efforts to ensure medication affordability for this population will be important in boosting adherence to key medications.
