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

Achieving a specific diagnosis of polycythemia vera (PV) and other myeloproliferative disorders (MPDs) is often costly and complex. However, the recent identification of a V617F mutation in the JH2 domain of the JAK2 gene in a high proportion of patients suffering from MPDs may provide confirmation of a diagnosis. This is an acquired mutation and, as such, may only be present in a small number of cells within a sample. There is therefore a clinical need for highly sensitive detection techniques. We have developed a sensitive real-time polymerase chain reaction (PCR)-based approach for both detection and quantification of the JAK2 V671F mutation load, which allows determination of mutation status without the need for prior purification of granulocytes. We have performed a comparison of this assay with two previously published detection methods. Although an amplification refractory mutation system (ARMS) was shown to be slightly superior in terms of sensitivity, our real-time PCR method provides the potential for quantification of the JAK2 V617F mutation, having potential future applications in the monitoring of minimal residual disease or predicting outcome of disease severity.
