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

PTPN11, which encodes the tyrosine phosphatase SHP2, is mutated in approximately 35% of patients with juvenile myelomonocytic leukemia (JMML) and at a lower incidence in other neoplasms. To model JMML pathogenesis, we generated knockin mice that conditionally express the leukemia-associated mutant Ptpn11(D61Y). Expression of Ptpn11(D61Y) in all hematopoietic cells evokes a fatal myeloproliferative disorder (MPD), featuring leukocytosis, anemia, hepatosplenomegaly, and factor-independent colony formation by bone marrow (BM) and spleen cells. The Lin(-)Sca1(+)cKit(+) (LSK) compartment is expanded and "right-shifted," accompanied by increased stem cell factor (SCF)-evoked colony formation and Erk and Akt activation. However, repopulating activity is decreased in diseased mice, and mice that do engraft with Ptpn11(D61Y) stem cells fail to develop MPD. Ptpn11(D61Y) common myeloid progenitors (CMPs) and granulocyte-monocyte progenitors (GMPs) produce cytokine-independent colonies in a cell-autonomous manner and demonstrate elevated Erk and Stat5 activation in response to granulocyte-macrophage colony-stimulating factor (GM-CSF) stimulation. Ptpn11(D61Y) megakaryocyte-erythrocyte progenitors (MEPs) yield increased numbers of erythrocyte burst-forming units (BFU-Es), but MEPs and erythrocyte-committed progenitors (EPs) produce fewer erythrocyte colony-forming units (CFU-Es), indicating defective erythroid differentiation. Our studies provide a mouse model for Ptpn11-evoked MPD and show that this disease results from cell-autonomous and distinct lineage-specific effects of mutant Ptpn11 on multiple stages of hematopoiesis.
