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

The identification of genetic variants in melanoma has enabled the development of targeted therapies. Under the National Institute for Health and Care Excellence (NICE) guidance, patients with BRAF V600E variant are eligible for BRAF and MEK inhibitor therapy. For those with advanced or highly symptomatic disease, a rapid response to treatment is often seen. Current practice relies on tissue biopsy to perform immunohistochemistry (IHC) or next generation sequencing (NGS) to identify these variants; however, this can take up to 2 weeks. In patients with widespread disease, rapid initiation of treatment can be lifesaving.We describe a case in which hotspot circulating tumour DNA (ctDNA) analysis confirmed BRAF variant 6 days prior to biopsy results. This was utilised to expedite treatment initiation and symptomatically, the patient had initial improvement within a few days.This article demonstrates the potential value of ctDNA analysis and the need for further research into this as an alternative to NGS for patients with rapidly progressive disease.
