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

backgroundWe have shown that fresh frozen plasma's (FFP) protection of pulmonary endothelial barrier integrity following hemorrhagic shock is due in part to restoration of endothelial syndecan-1. In the present study, we investigated the role of fibrinogen, a major component of FFP, as an endothelial protector and hypothesize that fibrinogen stabilizes cell surface syndecan-1 to restore endothelial barrier integrity.

methodsPulmonary endothelial cells were incubated in FFP, fibrinogen, or lactated Ringers (LR) then immunostained with anti-syndecan-1 or fibrinogen and barrier integrity assessed. In some experiments, cells were exposed to fibrinogen depleted plasma.

resultsCell surface syndecan-1 was increased by FFP and fibrinogen compared with LR-treated cells while barrier integrity was augmented by FFP and fibrinogen compared with LR. The physiological concentration of 2.5 mg/mL fibrinogen was sufficient to increase cell surface syndecan-1. Colocalization and co-immunoprecipitation experiments demonstrated that fibrinogen associates with syndecan-1. Fibrinogen-deficient plasma was unable to augment sydnecan-1 immunostaining and lost its endothelial protective effect on barrier integrity.

conclusionThese data suggest that in vitro, fibrinogen associated with cell surface syndecan-1 and enhanced endothelial barrier integrity.
