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

Fifty-two samples of pediatric low-grade glioma (48 primary, 4 recurrent) were analyzed for BRAF copy number variation (digital PCR analysis, CopyCaller) and point mutations of BRAF V600E, and exon 5 Q209 in GNAQ, and GNA11, using the MALDI-TOF mass spectrometer with validation by direct sequencing. An increased BRAF copy number was found in 18/47 primary samples tested; 15 of them (83.3%) were pilocytic astrocytomas. A BRAF mutation was found in 3/48 primary tumors, all with a normal BRAF copy number and no GNAQ mutation. One sample had a GNAQ209 mutation (Q209P626) with a normal BRAF gene; none of the tumors had a GNA11Q209 mutation. Recurrent or progressive tumors, analyzed in four patients, had the same molecular genotype as their primary. Increased BRAF copy number and activating BRAF mutations may be involved in the development of low-grade glioma via overactivation of the Ras/Raf pathway. This is the first report of a mutation in GNAQ209 in pediatric low-grade glioma. Understanding the molecular mechanisms underlying glioma initiation and growth may assist in the development of targeted therapies.
