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 analysis of KRAS mutations has become a prerequisite for anti-epidermal growth factor receptor therapy in patients with metastatic colorectal cancers. KRAS mutations are associated with resistance to treatment by monoclonal antibodies such as cetuximab and panitumumab and thus are correlated with a shorter progression-free survival. BRAF mutations also may play a role in treatment decisions. The widespread use of these targeted therapies has generated the need to develop cost-effective methods for routine KRAS and BRAF analysis. The aim of this study was to compare a multiplex SNaPshot assay with DNA sequencing and high-resolution melting analysis for identifying KRAS codons 12 and 13 and BRAF codon 600 mutations. Thus 110 routinely formalin-fixed and paraffin-embedded tissue blocks were tested by each method. The SNaPshot analysis detected KRAS and BRAF codon 600 mutations in, respectively, 34.5% (n = 38) and 10% (n = 11) of these tissue blocks. These results were confirmed by direct DNA sequencing and by high-resolution melting analysis. The costs and time constraints of each detection method were compared at the same time. In conclusion, our newly designed multiplex SNaPshot assay is a fast, inexpensive, sensitive, and robust technique for molecular diagnostic practices and patient selection.
