Necessity of Prophylactic Anticoagulation Therapy Following Inferior Vena Cava Stent Placement in Patients with Cancer.

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
Purpose: Although percutaneous stent placement for malignant inferior vena cava syndrome is a highly feasible and effective treatment option, there is no clear evidence for the necessity of prophylactic anticoagulation therapy after inferior vena cava stent placement. This study retrospectively evaluated the necessity of prophylactic anticoagulation following inferior vena cava stent placement in patients with malignant inferior vena cava syndrome. Methods: The data of 54 patients (28 men and 26 women; median age 61.2 years) with malignant inferior vena cava syndrome who received inferior vena cava stent placement between 2011 and 2021 were retrospectively reviewed. Prophylactic anticoagulation was administered to 15 of 54 patients (27.8%) following stent placement. Symptom recurrence rates at 1 and 2 months after stent placement were compared between patients with and without prophylactic anticoagulation using Gray relational analysis. The timeline of symptom recurrence, survival time, and adverse events were also evaluated. Results: At 1 and 2 months, symptom recurrence rates were 48.6% and 71.4%, respectively, in patients with prophylactic anticoagulation and 28.3% and 37.0%, respectively, in patients without prophylactic anticoagulation. The overall median follow-up duration was 27 days and that of the patients with and without prophylactic anticoagulation was 37 and 25 days, respectively. The median survival times of patients with and without anticoagulation therapy were 69 and 30 days, respectively (p = 0.236). No procedure-related complications occurred. Conclusions: There was no significant difference in the symptom recurrence rates after inferior vena cava stent placement with or without prophylactic anticoagulation in this study.
