The thrombin receptor PAR1 orchestrates changes in lymphatic endothelial cell junction morphology to augment lymphatic drainage during lung injury.

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
The lung lymphatic vasculature is capable of remarkable increases in lymphatic drainage in settings of inflammation and edema; however, the mechanisms driving this are not clear. Here we show that lung injury transforms the configuration of lung lymphatic endothelial cell junctions from a continuous 'zippered' configuration to a discontinuous and permeable 'button' configuration. Despite similarity to the junctional changes often seen in leaky and dysfunctional blood vessels, we find that the shift to button junctions in the lymphatic vasculature has an opposite effect, resulting in augmented lung lymphatic drainage. Mechanistically, we demonstrate that lung lymphatic button junction formation in models of lung injury is dependent on the thrombin receptor protease-activated receptor 1, a known mediator of blood vessel permeability. These results uncover a previously unknown role for the thrombin receptor protease-activated receptor 1 in the lymphatic vasculature that promotes a similar change in junction morphology as seen in blood vessels, but with a disparate effect on lymphatic function.
