Molecular-genetic and clinical characteristics of gliomas with astrocytic appearance and total 1p19q loss in a single institutional consecutive cohort.
Article in Oncotarget, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The prognostic significance of 1p19q loss in astrocytic gliomas has been inconclusive.We collected 57 gliomas with total 1p19q loss from among 218 cases of WHO grade-II/III gliomas operated at Keio University Hospital between 1990 and 2010. These tumors were classified as oligodendroglial or "astrocytic" by a WHO-criteria-based institutional diagnosis. Chromosomal copy number aberrations (CNAs), IDH 1/2 mutations, MGMT promoter methylation, and expression of p53 and ATRX were assessed. Survival outcome was compared between the two histological groups.Of the 57 codeleted gliomas, 37, 16, and four were classified as oligodendroglial, "astrocytic", and unclassified, respectively. Comparative genomic hybridization revealed that although chromosome 7q/7 gain was more frequent in "astrocytic" gliomas, other CNAs occurred at a similar frequency in both groups. None of the "astrocytic" gliomas showed p53 accumulation, and ATRX loss was found in three of the 15 "astrocytic" gliomas. The estimated overall survival (OS) curves in the patients with codeleted oligodendroglial and "astrocytic" gliomas overlapped, and the median OS was 187 and 184 months, respectively. Histopathological re-assessment by a single pathologist showed consistent results.Gliomas with total 1p19q loss with "astrocytic" features have molecular and biological characteristics comparable to those of oligodendroglial tumors.
