The Role of the VWF/ADAMTS13 Axis in the Thromboinflammatory Response in Ischemic Stroke After SARS-CoV2 Infection.

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
backgroundSARS-CoV2 infections increase the risk of ischemic stroke (IS), potentially through a thromboinflammatory cascade driven by an imbalance in the ratio of Von Willebrand Factor (VWF) and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13), leading to the formation of ultra-large VWF (UL-VWF). However, the SARS-CoV2 infection's contribution to any VWF/ADAMTS13 axis imbalance and the subsequent thromboinflammatory response post-stroke remain poorly understood.
methodsWe performed a detailed thromboinflammatory profile of the plasma samples from three experimental cohorts matched by age, sex, and stroke severity: non-stroke controls (n = 23), SARS-CoV2 negative IS (n = 22), and SARS-CoV2 positive IS (n = 24). SARS-CoV2 positive IS patients presented varying degrees of infection severity.
resultsWe observed an increase in VWF and UL-VWF and a decrease in ADAMTS13 in the SARS-CoV2 positive IS cohort, suggesting a VWF/ADAMTS13 axis imbalance. Interleukin-6 (IL-6) levels were positively correlated with VWF and negatively correlated with ADAMTS13, suggesting that IL-6 may drive this imbalance. Fibrinogen and D-Dimers were elevated in SARS-CoV2 negative IS cohort and SARS-CoV2 positive IS cohort, but D-Dimers were within the normal range, indicating no disseminated intravascular coagulation. Factor IX (FIX) was elevated in the SARS-CoV2 negative IS cohort. Tissue plasminogen activator (tPA) was elevated in the SARS-CoV2 positive IS cohort, suggesting no fibrinolysis defects. Matrix Metalloproteinase-2 (MMP-2) and soluble Intracellular Adhesion Molecule-1 (sICAM-1) were elevated in the SARS-CoV2 negative IS cohort.
conclusionsWe show that SARS-CoV2 infections drive a VWF/ADAMTS13 axis imbalance, inducing an increase in tPA while decreasing FIX, MMP-2, and sICAM-1 post-stroke.
