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

Myocardial inflammatory responses to endotoxemia are enhanced in old mice, which results in worse cardiac dysfunction. Anti-inflammatory cytokine interleukin (IL)-37 has a broad effect on innate immunoresponses. We hypothesized that IL-37 suppresses myocardial inflammatory responses to protect cardiac function during endotoxemia in old mice. Old (20-24month) wild-type (WT), and IL-37 transgenic (IL-37tg) mice were treated with lipopolysaccharide (LPS, 0.5mg/kg, iv) or normal saline (0.1ml/mouse, iv). Six hours later, left ventricle (LV) function was assessed using a pressure-volume microcatheter. Levels of monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-6 in plasma and myocardial tissue, as well as mononuclear cell density in the myocardium, were examined. Cardiac microvascular endothelial cells isolated from WT and IL-37tg mice were treated with LPS (0.2µg/ml) for 0.5-24h. Nuclear factor-kappa B (NF-κB) p65 phosphorylation was examined by immunoblotting, and MCP-1 levels in cell culture supernatant was determined using enzyme-linked immunosorbent assay. LV dysfunction in old WT endotoxemic mice was accompanied by up-regulated MCP-1, myocardial accumulation of mononuclear cells and production of TNF-α, IL-1β and IL-6. Expression of IL-37 suppressed myocardial inflammatory responses to endotoxemia in old mice, resulting in improved LV function. Treatment of old WT endotoxemic mice with recombinant IL-37 also improved LV function. In vitro experiments revealed that cardiac microvascular endothelial cells from IL-37tg mice had attenuated NF-κB activation and MCP-1 production following LPS stimulation. In conclusion, IL-37 is potent to suppress myocardial inflammation and protects against cardiac dysfunction during endotoxemia in old mice.
