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

objectivePolycythemia vera (PV) is a clonal myeloproliferative neoplasia associated with the activation of the Janus-activating kinase 2 (JAK2) mutation. The aim of this study is to identify clonal expansion of exon 12 mutations.

methodsWe performed DNA sequencing of the JAK2 exon 12 after TA-cloning in JAK2-V617F-negative and JAK2-V617F-positive PV patients. RESULTS AND

conclusionsWe found clonal mutations (i.e. H538-K539delinsL and D544G) in 3 of 7 JAK2-V617F-negative PV patients, however, unlike JAK2-V617F, allele burden of JAK2 exon 12 mutation was low. Since allele-specific PCR is able to amplify only the limited region which contains known mutations with gain-of-function, we need to clarify the biological implications of unknown single nucleotide substitution of the JAK2 exon 12 with low clonal burden in erythrocytosis patients.
