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

introductionIn hemorrhagic shock (HS), plasma resuscitation preserves vascular integrity and protects against trauma-induced coagulopathy and organ injury. Despite demonstrated clinical benefit, the endothelial mechanisms underlying plasma resuscitation remain incompletely defined. This study investigated endothelial-specific responses to plasma resuscitation to identify targetable pathways that promote vascular repair after traumatic injury.

methodsA murine model of severe polytrauma-HS (PT/HS) with demonstrable vascular endotheliopathy by 24 hours was used to compare pulmonary vascular endothelial cell (EC) responses to resuscitation with lactated Ringer's solution (LR) relative to fresh frozen plasma (FFP). Whole blood was collected for inflammatory biomarker analysis, and pulmonary vascular leak was quantified by dextran extravasation. Pulmonary EC glycocalyx structure was assessed by transmission electron microscopy and immunofluorescence. Spatial transcriptomic profiling of pulmonary ECs was performed using a GeoMx Digital Spatial Profiler. Key transcriptomic findings related to mitochondrial biogenesis were validated by immunostaining and by treating primary human lung EC with FFP or LR.

resultsAt 24 hours after injury, FFP reduced systemic inflammatory cytokines, pulmonary innate immune cell infiltration, and PT/HS-induced vascular leak compared to LR. Plasma levels of syndecan-1 and hyaluronan were decreased, consistent with a reduction in pulmonary glycocalyx shedding. Although few differences in EC glycocalyx-related genes were detected, pathway analysis revealed enrichment of cellular bioenergetics and metabolic recovery pathways in ECs after FFP, whereas LR was associated with oxidative stress and inflammatory signaling. FFP enhanced mitochondrial content in pulmonary EC after PT/HS and in treated human EC compared to LR-treated controls.

conclusionsFFP resuscitation after PT/HS reduces systemic inflammation and preserves pulmonary vascular barrier function, potentially through promotion of mitochondrial signaling, metabolic recovery, and endothelial stress regulation.
