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

Studies have shown that mutant calreticulin (CALR) constitutively activates the thrombopoietin (TPO) receptor MPL and thus plays a causal role in the development of myeloproliferative neoplasms (MPNs). To further elucidate the molecular mechanism by which mutant CALR promotes MPN development, we studied the subcellular localization of mutant CALR and its importance for the oncogenic properties of mutant CALR. Here, mutant CALR accumulated in the Golgi apparatus, and its entrance into the secretion pathway and capacity to interact with N-glycan were required for its oncogenic capacity via the constitutive activation of MPL. Mutant CALR-dependent MPL activation was resistant to blockade of intracellular protein trafficking, suggesting that MPL is activated before reaching the cell surface. However, removal of MPL from the cell surface with trypsin shut down downstream activation, implying that the surface localization of MPL is required for mutant CALR-dependent activation. Furthermore, we found that mutant CALR and MPL interact on the cell surface. Based on these findings, we propose a model in which mutant CALR induces MPL activation on the cell surface to promote MPN development.
