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

Exposure to trichloroethene (TCE), a ubiquitous environmental contaminant, is known to induce autoimmunity both in humans and animal models. However, mechanisms underlying TCE-mediated autoimmunity remain largely unknown. Previous studies from our laboratory in MRL+/+ mice suggest that oxidative stress may contribute to TCE-induced autoimmune response. The current study was undertaken to further assess the role of oxidative stress in TCE-induced autoimmunity by supplementing with an antioxidant N-acetylcysteine (NAC). Groups of female MRL+/+ mice were given TCE, NAC or TCE+NAC for 6 weeks (TCE, 10mmol/kg, i.p., every 4th day; NAC, 250mg/kg/day through drinking water). TCE exposure led to significant increases in serum levels of anti-nuclear, anti-dsDNA and anti-Sm antibodies. TCE exposure also led to significant induction of anti-malondiadelhyde (MDA)- and anti-hydroxynonenal (HNE)-protein adduct antibodies which were associated with increased ANA in the sera along with increased MDA-/HNE-protein adducts in the livers and kidneys, and increases in protein oxidation (carbonylation) in the sera, livers and kidneys, suggesting an overall increase in oxidative stress. Moreover, TCE exposure also resulted in increased release of IL-17 from splenocytes and increases in IL-17 mRNA expression. Remarkably, NAC supplementation attenuated not only the TCE-induced oxidative stress, IL-17 release and mRNA expression, but also the markers of autoimmunity, as evident from decreased levels of ANA, anti-dsDNA and anti-Sm antibodies in the sera. These results provide further support to a role of oxidative stress in TCE-induced autoimmune response. Attenuation of TCE-induced autoimmunity in mice by NAC provides an approach for preventive and/or therapeutic strategies.
