Temporal trends and risk factors of gastrointestinal bleeding in patients with left ventricular assist devices: a nationwide analysis 2008-2017.

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: Left ventricular assist devices (LVADs) are indicated for patients with end-stage heart failure and require systemic anticoagulation. Gastrointestinal (GI) bleeding is a major adverse event following LVAD implantation. There is paucity of data on healthcare resource utilization in patients with LVAD and the risk factors of associated bleeding, despite the increase in GI bleeding. We investigated the in-hospital outcomes of GI bleeding in patients with continuous-flow (CF) LVAD. Methods: This was a serial cross-sectional study of the Nationwide Inpatient Sample (NIS) in the CF-LVAD era from 2008-2017. All adults admitted to hospital with a primary diagnosis of GI bleeding were included. GI bleeding was diagnosed by ICD-9/ICD-10 codes. Patients with CF-LVAD (cases) and without CF-LVAD (controls) were compared using univariate and multivariate analyses. Results: A total of 3,107,471 patients were discharged with a primary diagnosis of GI bleeding during the study period. Of these, 6569 (0.21%) had CF-LVAD-related GI bleeding. Overall, bleeding angiodysplasia accounted for the majority (69%) of LVAD-related GI bleeding. There was no statistical difference in mortality, but the length of hospital stay increased by 2.53 days (95% confidence interval [CI] 1.78-2.98; P<0.001) and the mean hospital charge per stay increased by $25,980 (95%CI 21,267-29,874; P<0.001) in 2017 compared to 2008. The results were consistent after propensity score matching. Conclusion: Our study highlights that patients with LVAD admitted to the hospital for GI bleeding experience longer hospital stays and greater healthcare costs that warrant risk-based patient evaluation and careful implementation of management strategies.
