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.

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.

Abstract

backgroundGliomas represent about 80% of primary brain tumours and about 30% of malignant ones, which today don't have a resolution therapy because of their variability. A valid model for the study of new personalized therapies can be represented by primary cultures from patient's tumour biopsies.

methodsIn this study we consider 12 novel cell lines established from patients' gliomas and immunohistochemically and molecularly characterized according to the newly updated 2016 CNS Tumour WHO classification.

resultsEight of these lines were glioblastoma cells, two grade III glioma cells (anaplastic astrocytoma and oligo astrocytoma) and two low grade glioma cells (grade II astrocytoma and oligodendroglioma). All cell lines were analysed by immunohistochemistry for specific glioma markers, respectively VIMENTIN, GFAP, IDH1R132, and ATRX. The methylation status of the MGMT gene promoter was also determined in all lines. The comparison of the immunohistochemical characteristics and of the MGMT methylation status of the lines with the tissues of origin shows that the cells in culture maintain the same characteristics.

conclusionsHuman cancer cell lines represent a support in the knowledge of tumour biology and in drug discovery through its facile experimental manipulation.
