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

objectiveThe anti-inflammatory properties of the female sex hormone estrogen have been linked to a reduced incidence of cardiovascular disease. In the present study, we addressed whether estrogen could activate vasculoprotective mechanisms via annexin A1 (AnxA1) mobilization in human polymorphonuclear cells (PMNs). METHODS AND

resultsUsing whole-blood flow cytometry, we demonstrated that premenopausal women expressed higher levels of surface AnxA1 on circulating PMNs compared with males. This correlated with high plasma estrogen during the menstrual cycle. The addition of estrogen in vitro to male PMNs induced rapid mobilization of AnxA1, optimal at 5 ng/mL and a 30-minute incubation period; this effect was abolished in the presence of the estrogen receptor antagonist ICI182780. Estrogen addition to human PMNs induced a distinct AnxA1(hi) CD62L(lo) CD11b(lo) phenotype, and this was associated with lower cell activation as measured by microparticle formation. Treatment of human PMNs with E(2) inhibited cell adhesion to an endothelial cell monolayer under shear, which was absent when endogenous AnxA1 was neutralized. Of interest, addition of estrogen to PMNs flowed over the endothelial monolayer amplified its upregulation of AnxA1 localization on the cell surface. Finally, in a model of intravital microscopy, estrogen inhibition of white blood cell adhesion to the postcapillary venule was absent in mice nullified for AnxA1.

conclusionWe unveil a novel AnxA1-dependent mechanism behind the inhibitory properties of estrogen on PMN activation, describing a novel phenotype with a conceivable impact on the vasculoprotective effects of this hormone.
