The relationship between emergency department use and cost-related medication nonadherence among Medicare beneficiaries.
Article in Annals of emergency medicine, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
STUDY
objectiveThe objective of this study was to evaluate the relationship between self-reported cost-related nonadherence to prescription medications and emergency department (ED) utilization among Medicare beneficiaries. We hypothesized that persons who report cost-related medication nonadherence would have subsequent higher ED use.
methodsWe conducted a retrospective cohort study of continuously enrolled Medicare beneficiaries in 2006 and 2007. We used multivariate logistic regression to evaluate the relationship between ED use and cost-related medication nonadherence. Our principal dependent variable was any ED visit within a 364-day period after an interview assessing cost-related medication nonadherence. Our principal independent variables both denoted cost-related medication nonadherence: mild cost-related medication nonadherence, defined as a reduction in dose or a delay in filling medications because of cost; and severe cost-related medication nonadherence, defined as not filling a medication at all because of cost.
resultsOur sample consisted of 7,177 Medicare Current Beneficiary Survey respondents. Approximately 7.5% of respondents reported mild cost-related medication nonadherence only (n=541) and another 8.2% reported severe cost-related medication nonadherence (n=581). Disabled Medicare beneficiaries with severe cost-related medication nonadherence were more likely to have at least 1 ED visit (1.53; 95% confidence interval 1.03 to 2.26) compared with both disabled Medicare beneficiaries without cost-related medication nonadherence and elderly Medicare beneficiaries in all cost-related medication nonadherence categories.
conclusionOur results show an association between severe cost-related medication nonadherence and ED use. Disabled beneficiaries younger than 65 years who report severe cost-related medication nonadherence were more likely to have at least 1 ED visit, even when adjusting for other factors that affect utilization.
