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

Mutations in the BRAF gene are found in the majority of cutaneous malignant melanomas and subsets of other tumors. These mutations lead to constitutive activation of BRAF with increased downstream ERK (extracellular signal-regulated kinase) signaling; therefore, the development of RAF kinase inhibitors for targeted therapy is being actively pursued. A methodology that allows sensitive, cost-effective, high-throughput analysis of BRAF mutations will be needed to triage patients for specific molecular-based therapies. Pyrosequencing is a high-throughput, sequencing-by-synthesis method that is particularly useful for analysis of single nucleotide polymorphisms or hotspot mutations. Mutational analysis of BRAF is highly amenable to pyrosequencing because the majority of mutations in this gene localize to codons 600 and 601 and consist of single or dinucleotide substitutions. In this study, DNAs from a panel of melanocyte cell lines, melanoma cell lines, and melanoma tumors were used to validate a pyrosequencing assay to detect BRAF mutations. The assay demonstrates high accuracy and precision for detecting common and variant exon 15 BRAF mutations. Further, comparison of pyrosequencing data with 100K single nucleotide polymorphism microarray data allows characterization of BRAF amplification events that may accompany BRAF mutation. Pyro-sequencing serves as an excellent platform for BRAF genotyping of tumors from patients entering clinical trial.
