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: Inflammation is a driver of thrombosis, but the phenomenon of thromboinflammation has been defined only recently, bringing together the multiple pathways involved. Objectives: To develop a model for thrombin generation (TG) on the surface of human endothelial cells (ECs) to assess pro/antithrombotic properties in response to inflammation. Furthermore, to elucidate the mechanisms of TG regulation and its modulation by immunomodulatory therapies. Methods: Cytokine-induced (tumor necrosis factor [TNF]-α, interleukin [IL]-1β, and interferon-γ) effects on ECs isolated from umbilical veins or human aortic tissue were assessed using calibrated automated thrombography in platelet-poor plasma. The expression of key coagulant and inflammatory regulators was measured at the mRNA level. Tissue factor (TF) protein levels were further assessed by flow cytometry. Results: Endothelial stimulation with TNF-α or IL-1β caused ECs to trigger TG without the addition of exogenous TF, with higher TG observed after 6 hours of stimulation than 24 hours. IL-1β induced higher peak thrombin (170 ± 5.9 nM vs 115 ± 4.9 nM), endogenous thrombin potential (1632 ± 35 nM ∗ min vs 1370 ± 23 nM ∗ min) presented as mean ± SD, and TF expression (∼2.8-fold higher) compared with TNF-α at 6 hours. Interferon-γ stimulation failed to induce TG and TF expression. The immunomodulatory drug, hydroxychloroquine, reduced cytokine-induced TG and downregulated TF expression. Conclusion: We provide detailed optimization of a robust
