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 aim of this study was to elucidate the role of a non-canonical JAK2 mutation JAK2-T875N, which was identified by exome sequencing in a patient with essential thrombocytosis (ET) who had a family history of suspecting ET. Whole exome sequencing was performed on peripheral blood mononuclear cells and buccal swab-derived genomic DNA. Sanger sequencing was performed to confirm the variant. We evaluated the function of the mutation on JAK2 activity and downstream signaling (Erk, STATs) using JAK2-T875N-transfected or transduced cell lines. 293T cells transfected with JAK2 cDNA carrying V617F or T875N mutations showed increased levels of phosphorylated JAK2 and Erk. Enhanced STAT3 and STAT5 activity was confirmed by promoter assay. JAK2-T875N-transduced Ba/F3 cells showed increased cellular growth without IL-3 stimulation. To our knowledge, this is the first case of ET caused by JAK2-T875N mutation with a family history of thrombocytosis and cerebral infarction.
