Cyto/Genotoxicity study of polyoxyethylene (20) sorbitan monolaurate (tween 20).
Article in DNA and cell biology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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.
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
Polyoxyethylene (20) sorbitan monolaurate (tween 20) is a non-ionic surfactant that is widely used as an emulsifier and stabilizer in pharmaceutical formulations, food and cosmetic industries. Although a number of studies have showed its non-toxic impacts on target cells, still, it is essential to investigate its effect on target cells. Therefore, in the present study, the anti-cell proliferation and cyto/genotoxicity effects of tween 20 are reported to address the possible mechanism for induction of apoptosis. At 40%-50% confluency, A549 cells and human umbilical vein endothelial cells were exposed to tween 20 at a recommended concentration for 24 h. After 24 h, to detect apoptosis and DNA damage, the treated cells were subjected to 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, fluorescein isothiocyanate (FITC)-labeled annexin V flow cytometry, DAPI staining, comet, and DNA ladder assays. Tween 20 decreased the growth of treated cells dose and time dependently, and single-strand DNA cleavage has been confirmed by comet assay. In addition, morphological alteration of DAPI-stained cells showed clear fragmentation in the chromatin and DNA rings within the nucleus of tween 20-treated cells. In addition, flow cytometry and DNA fragmentation assays confirmed DAPI staining assay results and indicated the occurrence of a programmed cell death (apoptosis) in the treated cells. These results demonstrate that, despite consideration of tween 20 as a safe non-ionic surfactant, it can induce apoptosis in target cells.
