Outcomes of Asian-Americans Implanted With Left Ventricular Assist Devices: An Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) Analysis.
Article in Heart, lung & circulation, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundStudies have indicated differences between Asians and Whites in their propensity for stroke, coronary artery disease, heart failure, bleeding and thrombosis. We investigated whether Asian-Americans on durable left ventricular assist devices (LVADs) exhibit differential morbidity and mortality when compared to Whites.
methodsWe analysed prospectively collected data from the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) database to compare the outcomes after LVAD implantation of Asians versus Whites.
resultsIn total, 7,018 patients were included, 130 were identified as Asian-Americans. Asian-Americans were younger, had lower body mass index, higher serum bilirubin and lower albumin levels. In a multivariable regression model, there was no difference in survival between the two groups. Asian-Americans had lower incidence of device malfunction and after adjusting for multiple factors this remained lower. The adjusted risk of a major safety composite outcome, including major bleeding, major infection, stroke and device malfunction, revealed no difference between the two groups.
conclusionsAlthough prior studies have reported worse cardiac surgery outcomes in Asians, in this INTERMACS analysis Asian-Americans appear to have similar survival and risk of adverse events as their White counterparts. The incidence of device malfunction was lower in the Asian-Americans, both in a univariate model and after adjusting for multiple clinical factors. Future, larger studies of Asian-Americans with end-stage heart failure and LVAD support are warranted to confirm these results.
