Molecular heterogeneity characterizes glioblastoma with lipoblast/adipocyte-like cytology.

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
Glioblastoma, the most common primary brain tumor in adults, may rarely show among unusual histological patterns lipoblast/adipocyte-like features. The genetic features of such cases are not yet well characterized, and molecular data are available for only few cases. In order to further expand our knowledge about their molecular profile, we analyzed four cases of glioblastoma with adipocyte-like features. Multiplex ligation-dependent probe amplification (MLPA) revealed loss of PTEN and MDM2 amplification in two cases while another case was characterized by CDKN2A deletion. Conversely, we did not find any evidence of EGFR amplification, BRAF (V600E) or IDH1/2 mutations. Our results, along with data published in previous studies, showed that glioblastoma with lipoblast/adipocyte-like cytology present a heterogeneous genetic background and therefore seem to represent more a rare phenotypic variant than a specific tumor subtype.
