Risk factors for thromboembolic events in pediatric patients with ventricular assist devices.
Article in JTCVS open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: Pediatric patients on ventricular assist devices (VAD) are at risk of thromboembolic (TE) complications. Our objective was to identify factors associated with TE events, including the role of initial anticoagulation strategy and device type in the pediatric VAD population. Methods: This was a retrospective, single-center review (2005-2022) of children who were implanted with paracorporeal pulsatile (PP), paracorporeal continuous (PC), or a combination of devices. Patient- and device-related factors were collected. Kaplan-Meier survival analysis was performed to determine freedom from TE. Cox proportional hazard analysis was conducted to look for factors associated with TE events. Results: Ninety-five patients included with a median age of 0.9 years (interquartile range, 0.3, 5.4); median weight of 8.4 kg (interquartile range, 4.5, 17.8), and 63.2% with noncongenital heart disease. Device breakdown included 47.4% PC, 24.2% PP, and 23.2% combination of devices. Initial anticoagulation was either heparin (61.5%) or bivalirudin (38.5%). In Kaplan-Meier analysis, unadjusted freedom from a TE event was significantly greater in those who received bivalirudin as their initial anticoagulation strategy ( Conclusions: This study suggests that PC device strategy and heparin as an initial anticoagulation strategy are associated with increased hazard of TE events. Further research is required to understand the interaction between device type and initial anticoagulation strategy.
