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

Although 1p19q codeleted gliomas are the most favorable molecular subgroup of lower-grade gliomas, there are cases with early recurrence or short survival. The objective of this study was to elucidate molecular-genetic and clinicopathological prognostic factors in patients with gliomas showing total 1p19q loss. The study included 57 consecutive patients with codeleted gliomas who were operated at Keio University Hospital between 1990 and 2010. These patients were assessed for chromosomal copy number aberrations, promoter methylation status of the O6-methylguanine-DNA methyltransferase gene (MGMT), and demographic and clinicopathological prognostic factors in diffuse gliomas. No significant difference was observed in the overall survival (OS) of the patients with respect to age (≥40 years vs. <40 years), degree of resection, maximum tumor diameter (≥5 cm vs. <5 cm), histological subtype, and MGMT promoter methylation status. Gain of chromosome 19p and grade III histology were associated with shorter OS (P = 0.019, 0.061, respectively). Gain of 19p and histological grade III might be negative prognostic factors for the patients with gliomas showing total 1p19q loss. Further investigation is warranted to confirm these notions.
