Disparities and Temporal Trends in Stroke Care Outcomes in Patients with Atrial Fibrillation: The FLiPER-AF Stroke Study.
Article in International journal of cerebrovascular disease and stroke, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
background and purposeAtrial Fibrillation (AF) is the most common cardiac cause of ischemic stroke. However, the relation between AF and stroke care outcomes in diverse populations is understudied. We aimed to evaluate sex and race-ethnic disparities associated with AF in hospital stroke outcomes utilizing data from the FLorida PuErto Rico Atrial Fibrillation (FLiPER-AF) Stroke Study.
methodsThe study included 104,308 ischemic stroke cases with available information on AF status enrolled in a state-wide stroke registry from 2010 to 2016. Multivariable logistic regression models were performed to evaluate the association between AF and stroke outcomes and the modification effects on the associations by sex and by race-ethnicity, adjusted for socio-demographic status, vascular risk factors and stroke severity.
resultsAF was present in 23% of ischemic stroke cases. AF was associated with worse disability at discharge (OR=1.11, 95% CI, 1.04-1.18), less discharge to home (OR=0.89, 0.85-0.92), and longer length of hospital stay (LOS>6 days, OR=1.53, 1.46-1.60). Interaction analyses showed that the association between AF and less discharge to home was stronger in women than men (p for interaction <0.001), as well as in FL-whites than in FL-blacks, FL-Hispanics or PR-Hispanics (p for interaction=0.002). The association between AF and prolonged LOS was more prominent in PR-Hispanics than in FL-blacks, FL-Hispanics, or FL-whites (p for interaction <0.001). From 2010 to 2016, the effects of AF on hospital length of stay attenuated (p for interaction<0.001).
conclusionsAF was associated with poor disability at discharge, less discharge to home, and prolonged hospital length of stay for acute stroke care. The effect of AF on length of stay attenuated over time. Sex and race-ethnic disparities were observed in the effect of AF on being less discharge to home and prolonged hospital stay. Further research is needed to identify and modify the biologic and systems of care contributors to these disparities.
