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

At fertilization in sea urchin eggs, elevated cytosolic Ca2+ leads to the exocytosis of 15,000-18,000 1.3-microns-diam cortical secretory granules to form the fertilization envelope. Cortical granule exocytosis more than doubles the surface area of the egg. It is thought that much of the added membrane is retrieved by subsequent endocytosis. We have investigated how this is achieved by activating eggs in the presence of aqueous- and lipid-phase fluorescent dyes. We find rapid endocytosis of membrane into 1.5-microns-diam vesicles starting immediately after cortical granule exocytosis and persisting over the following 15 min. The magnitude of this membrane retrieval can compensate for the changes in the plasma membrane of the egg caused by exocytosis. This membrane retrieval is not stimulated by PMA treatment which activates the endocytosis of clathrin-coated vesicles. When eggs are treated with short wave-length ultraviolet light, cortical granule exocytosis still occurs, but granule cores fail to disperse. After egg activation, large vesicles containing semi-intact cortical granule protein cores are observed. These data together with experiments using sequential pulses of fluid-phase markers support the hypothesis that the bulk of membrane retrieval immediately after cortical granule exocytosis is achieved through direct retrieval into large endocytotic structures.
