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

backgroundThere is growing evidence that exposure to small size particulate matter increases the risk of developing cardiovascular disease.

methodsWe investigated plaque progression and vasodilatory function in apolipoprotein E knockout (ApoE(-/-)) mice exposed to TiO(2). ApoE(-/-) mice were intratracheally instilled (0.5 mg/kg bodyweight) with rutile fine TiO2 (fTiO2, 288 nm), photocatalytic 92/8 anatase/rutile TiO(2) (pTiO(2), 12 nm), or rutile nano TiO(2) (nTiO(2), 21.6 nm) at 26 and 2 hours before measurement of vasodilatory function in aorta segments mounted in myographs. The progression of atherosclerotic plaques in aorta was assessed in mice exposed to nanosized TiO(2) (0.5 mg/kg bodyweight) once a week for 4 weeks. We measured mRNA levels of Mcp-1, Mip-2, Vcam-1, Icam-1 and Vegf in lung tissue to assess pulmonary inflammation and vascular function. TiO(2)-induced alterations in nitric oxide (NO) production were assessed in human umbilical vein endothelial cells (HUVECs).

resultsThe exposure to nTiO(2) was associated with a modest increase in plaque progression in aorta, whereas there were unaltered vasodilatory function and expression levels of Mcp-1, Mip-2, Vcam-1, Icam-1 and Vegf in lung tissue. The ApoE(-/-) mice exposed to fine and photocatalytic TiO(2) had unaltered vasodilatory function and lung tissue inflammatory gene expression. The unaltered NO-dependent vasodilatory function was supported by observations in HUVECs where the NO production was only increased by exposure to nTiO(2).

conclusionRepeated exposure to nanosized TiO(2) particles was associated with modest plaque progression in ApoE(-/-) mice. There were no associations between the pulmonary TiO(2) exposure and inflammation or vasodilatory dysfunction.
