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

During exocytosis, secretory granules fuse with the plasma membrane and discharge their content into the extracellular space. The exocytosed membrane is then reinternalized in a coordinated fashion. A role of clathrin-coated vesicles in this process is well established, whereas the involvement of a direct retrieval mechanism (often called kiss and run) is still debated. Here we report that a significant population of docked secretory granules in the neuroendocrine cell line PC12 fuses with the plasma membrane, takes up fluid-phase markers, and is retrieved at the same position. Fusion allows for complete discharge of small molecules, whereas GFP-labeled neuropeptide Y (molecular mass approximately equal 35 kDa) is only partially released. Retrieved granules were preferentially associated with dynamin. Furthermore, recapture is inhibited by guanosine 5'-[gamma-thio]triphosphate and peptides known to block dynamin function. We conclude that secretory granules can be recaptured immediately after formation of an exocytotic opening by an endocytic reaction that is spatially and temporally coupled to soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE)-dependent fusion, but is not a reversal of the fusion reaction.
