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

Nanoparticles are increasingly used in various fields, including biomedicine and electronics. One application utilizes the opacifying effect of nano-TiO(2), which is frequently used as pigment in cosmetics. Although TiO(2) is believed to be biologically inert, an emerging literature reports increased incidence of respiratory diseases in people exposed to TiO(2). Here, we show that nano-TiO(2) and nano-SiO(2), but not nano-ZnO, activate the NLR pyrin domain containing 3 (Nlrp3) inflammasome, leading to IL-1β release and in addition, induce the regulated release of IL-1α. Unlike other particulate Nlrp3 agonists, nano-TiO(2)-dependent-Nlrp3 activity does not require cytoskeleton-dependent phagocytosis and induces IL-1α/β secretion in nonphagocytic keratinocytes. Inhalation of nano-TiO(2) provokes lung inflammation which is strongly suppressed in IL-1R- and IL-1α-deficient mice. Thus, the inflammation caused by nano-TiO(2) in vivo is largely caused by the biological effect of IL-1α. The current use of nano-TiO(2) may present a health hazard due to its capacity to induce IL-1R signaling, a situation reminiscent of inflammation provoked by asbestos exposure.
