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

Insulin-like growth factor (IGF)-II is a hormone with mitogenic activity for many cell types and tissues. We demonstrate that its intracellular processing and secretion strictly depend on the endoplasmic reticulum chaperone glucose-regulated protein (GRP) 94. GRP94 interacts physically and transiently with pro-IGF-II intermediates, and its activity is essential for secretion of active IGF-II, thus establishing IGF-II as a client of GRP94. Embryonic stem (ES) cells that lack GRP94 are hypersensitive to stress conditions such as serum deprivation and die by apoptosis because they cannot respond to the stress by producing active IGF-II. This chaperone-client interaction may explain the previously documented antiapoptotic activity of GRP94 in a number of stress responses.
