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
introductionPercutaneous left ventricular assist device (pLVAD) explant remains nonstandardized with potential complications of bleeding and thrombosis. Explant settings include percutaneous techniques in the catheterization laboratory (CL), manually at bedside (MB), and surgically in the operating room (OR).
objectiveIdentify high-risk features for explant-related complications, including indication for support, setting, and technique.
methodsPostexplant bleeding and thrombosis/limb ischemia were identified following pLVAD removals over 2 years at a multicenter healthcare system.
resultsOf 156 patients, bleeding (n = 26 [17%]) and thrombosis (n = 9 [6%]) occurred more often in patients with the peripheral arterial disease (PAD), female gender, anemia, and cardiogenic shock. OR explants had a higher combined endpoint (4/8 [50%]) versus CL (23/133 [17%], p < 0.05) driven by transfusion. There was no difference between OR versus MB (5/15 [33%], p = 0.66) or CL versus MB (p = 0.62). In shock patients, there was no difference between CL (7/30 [23%]) versus MB (5/15 [33%], p = 0.5) and OR (4/7 [57%], p = 0.16); or MB versus OR (p = 0.38). Average length of stay was significantly lower in the CL group versus MB and OR (3.6 ± 33.2 vs. 18.4 ± 10.9 vs. 28.1 ± 15.8 days, p < 0.0001). Preclosure in shock patients (5/25 [20%] vs. 11/27 [41%], p = 0.1383) and crossover balloon occlusion technique (9/44 [16%] vs. 25/112 [22%]; p = 1) were not associated with higher combined endpoints versus control.
conclusionRisk factors for pLVAD explant complications include PAD, female gender, and cardiogenic shock. There was no difference in complication rates between explant settings among cardiogenic shock patients, but shorter length of stay when performed in the CL. There was no difference in complication rates when using the crossover balloon occlusion technique.
