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
backgroundLittle data exists regarding the optimal antithrombotic strategy during S-ICD implantation to prevent pocket hematomas. This study explores the association between perioperative antithrombotic management and the occurrence of pocket hematoma following S-ICD implantation.
methodsAll patients who underwent de novo S-ICD implantation between February 2009 and January 2023 at Amsterdam UMC were included. Data was collected retrospectively from electronic patient records. Clinically significant pocket hematomas were defined as an accumulation of blood at the pocket site within 30 days after implantation.
resultsA total of 347 patients were included of which 224 (64.6%) patients used antithrombotic therapy pre-implantation. The median age at implantation was 50 years (IQR 36-61 years), 33.4% of the patients were female, and the majority of implants were intermuscular (90.2%). A total of 18 patients (5.2%) developed a clinically significant pocket hematoma. There were significantly more pocket hematomas in patients with continued vitamin K antagonists (VKA) compared to patients with interrupted VKA (27.3% (6/22) vs. 4.3% (2/47), respectively, p = 0.01), and continuation of VKA was an independent predictor for pocket hematoma formation in the VKA group (p = 0.04). Moreover, continuation of dual antiplatelet therapy (DAPT) with ticagrelor was associated with significantly more pocket hematomas post-implantation compared to continuation of DAPT with clopidogrel (4/12 vs. 1/28, respectively, p = 0.02).
conclusionContinuation of VKA during S-ICD implantation was associated with an increased risk of pocket hematoma formation compared to interruption of VKA. This supports the need for specific perioperative antithrombotic therapy guidelines for S-ICD implantations to reduce the risk of pocket hematomas.
