1 · What the graph read from it

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.

2 · The registry

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: Outflow graft obstruction (OGO) is a rare but potentially fatal complication of left ventricular assist device (LVAD) therapy. Timely diagnosis and intervention are critical to prevent hemodynamic compromise and death. Methods: We retrospectively reviewed 191 LVAD patients treated between January 2016 and April 2025. Seven (3.66%) had imaging-confirmed OGO. One died before intervention; 6 underwent intravascular ultrasound (IVUS)-guided stenting. LVAD flows, pressure gradient, and 12-month survival were analyzed. Results: Patients had a mean age of 59.0 ± 13.8 years with a mean LVAD support duration of 63.6 ± 25.3 months. After stenting, mean LVAD flow improved from 1.98 to 4.70 L/min ( Conclusion: Intravascular ultrasound-guided stenting of OGO is safe and effective. Timely intervention may improve survival. Further research is needed for optimal antiplatelet strategies in LVAD patients undergoing stenting for OGO.
