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

Extracellular histones released into the circulation following trauma, sepsis, and ARDS may act as potent damage-associated molecular pattern signals leading to multiple organ failure. Endothelial cell (EC) dysfunction caused by extracellular histones has been demonstrated in vitro and in vivo; however, precise mechanistic details of histone-induced EC dysfunction and exacerbation of ongoing inflammation remain poorly understood. This study investigated the role of extracellular histones in exacerbating preexisting endothelial dysfunction and acute lung injury. Histone subunits H3 and H4, but not H1, H2A, or H2B, induced permeability in human pulmonary EC. H3 and H4 at concentrations above 30 µg/mL caused EC inflammation reflected by activation of the NF-κB pathway, transcriptional activation, and release of cytokines and chemokines including IL-6 and IL-8, and increased mRNA and protein expression of EC adhesion molecules VCAM-1 and ICAM-1. Pharmacological inhibitors targeting Toll-like receptor TLR4 but not TLR2/6, blocked histone-induced EC dysfunction. H3 and H4 also strongly augmented EC permeability and inflammation caused by Gram-negative and Gram-positive bacterial particles, endotoxin, and TNFα. Heparin blocked histone-induced augmentation of EC inflammation caused by endotoxin and TNFα.
