Real-Time Analysis of the Log Files of the HeartWare Continuous-Flow Left Ventricular Assist Device for the Early Diagnosis of Pump Thrombosis: a Step Forward Toward Clinical Translation.
Article in Journal of cardiovascular translational research, 2022. 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
We evaluated the real-time diagnostic capability of a new tool enhancing early diagnosis of pump thrombosis (PT) of the HeartWare left ventricular assist device via time-frequency analysis (TFA) of the log files. We analyzed 173 log files, including 24 (14%) associated with a clinical diagnosis of PT and 149 (86%) controls. The 30-day log file records were discretized into consecutive windows of a 24-h duration, which were iteratively acquired and processed via TFA. This way, we simulated longitudinal acquisition of pump parameters and provided real-time analysis of consecutive data, thus resembling the clinical scenario. Sensitivity and specificity of the tool were 79% and 84%, respectively. Sensitivity against PT events with progressive "build-up" thrombus increased up to 95%, and early signs of a forthcoming PT were identified 10±8 days prior to its clinical manifestation. This study demonstrates high reliability and the potential for effective clinical translation of this prognostic tool.
